AMP Emails

Z 1. Marketers with experience in email outreach campaigns are aware of the importance of email marketing. It's a precise and proven marketing tactic in which every email campaign metric can be measured efficiently. Conversion rates, click-through rates, open rates, and delivery rates are essential metrics measured in an effective email campaign, which in turn helps measure the overall campaign success. 

Similarly, email verification and validation should not be underestimated as it plays a vital role in your campaign’s success. Validating and verifying the email addresses of the recipients before kicking off your email campaign helps in improving the campaign performance overall. 

This blog details the concept of email verification and validation, why it is done, and what tools you can use to carry out email verifications along with their unique capabilities.

## What is Email Verification?


The intricate part of email cleansing is called email verification, which ensures whether the recipient’s mailbox accepts emails and is active. Email verification also identifies different email address discrepancies and possible spam traps before it gets flagged by the ESPs (Email Service Providers) or ISPs (Internet Service Providers), which can cause severe damages to your reputation for a lifetime. In other words, email validation enhances deliverability by cleaning up your emails and helps deliver messages to your target audience. 

## How is Email Verification done?

Though many of us use email verifying tools, most of us don't have a clear understanding of how email verification is done. Below are a few steps that explain how email verifiers work and the process behind them.

**Syntax Check:** This is the first step in verifying an email address. It helps ensure whether the email address is correct, checks spelling, commas, spaces, special characters, and also whether the domain extensions are used in the right place. 

**Domain Check:** This is the second step in the email verification process. It checks whether the domain name used in the email address exists and is registered and whether it is working correctly on the domain it is hosted. 

**Email Ping:** The third important step in the email verification process is the technical process, which pings an EHLO message to the exact email address and then waits for the server's response. If there is a response, it indicates that the email address is correct, exists, and the server is active. 

## Benefits of Email Verification Services

There are different reasons why an email address may turn invalid or stop working. Sometimes it may be due to the human factor like the person changing their email address or technical glitches. 

Below are a few reasons why verifying your email lists before sending out an email campaign is essential. 

- **When the recipient changes their email service/provider:** Let’s say a person is using a local email service provider and then they switch to Gmail/Hotmail. In these cases, your emails will not be delivered to the recipient, though the old one may still be active. 

- **When the recipient changes their email ID within the same email service provider:** If a person uses the same email service provider but switches to a new email address, your emails will not deliver and bounce back immediately.  

- **When the recipient switches positions within a company:** Every employee will have a different email address based on their designation. C-level employees, mid-level, and Junior cadre employees have different email address formats. When a person is promoted from a junior position to a mid-level, their email address automatically becomes invalid, which can cause your email messages to bounce. 

- **When the recipient changes jobs:** Many decision-makers and specialists often change jobs every few years, and in this case, emails get redirected to another person or become unreachable when a person leaves the company. 

- **When the domain is dead, it's a familiar and technical reason for the email to be verified:** If you find any website unreachable, then it indicates that the mail server is down or the domain is dead. In this case, you can't deliver the message to your recipient. 

- **When the public email provider is down or dead:** There is no chance for the email message to reach the recipient if the server is down or when the email provider is out of business. Sometimes online email providers experience technical server problems or even shut their businesses. 

Apart from this, it’s also essential to ensure whether the email verifier supports other verification methods like deliverability check, domain check, and syntax check. 

It’s not necessary to verify every email address. It’s okay to verify the email lists obtained from untrusted sources or if it’s a new set of email lists. This can help save more time and money. 

Now that you are super clear about the importance of verifying emails and the working mechanism, the next step is to choose the right email verification tool.

## What should you look for in a good email verification tool?

- **Online tool:** Make sure that it is an online email verification tool that works as SaaS (Software-as-a-Service). These tools don't need any of your computer resources as they are easily accessible anywhere and anytime from any device. You also don’t use your own IP for the verification process instead it uses the service’s IPs which work way better.
- **Scalability:** The email verifier you choose should be capable of verifying both single email addresses and extensive email lists. Bigger email lists take time in some cases but mostly done instantly. 
- **Personal and corporate emails:** You need to ensure whether the email verifier can verify both private and corporate email addresses. 
- **Different verification mechanism:** The email verifier you choose should verify multiple aspects by running other validation mechanisms like email server ping, domain check, and syntax check. 
- **All-in-one/Connectivity/Integrations:** All these features are considered necessary because every email verification process makes use of email verifiers, and therefore it's good that your verifier is integrated or connected with different tools like email list management tools, email sending tools, email generation tools, and more.

What are the best email verification and validation tools?

Spam messages accounted for 53.95 percent of email traffic in March 2020. According to Global spam placement rate 2015-2018, 7% of total promotional email ends up in the spam folder. You put plenty of effort into integrating an email- choosing the right template, writing enticing email copy, sending your emails to innumerable recipients. When doing all this make sure your domain is not tricked into the spam folder due to someone else’s fault. Let’s look into what  Sender Policy Framework (SPF) is, how it works, and what are its benefits.

## What is SPF for emails?

The sender policy framework is a technical layer to filter out hackers from spamming, spoofing, and phishing the receivers. It works as an email authentication method to safeguard email senders and their recipients. 
The Sender Policy Framework (SPF) is a form of email authentication that determines the mail servers that are allowed to deliver mails for your domain. SPF helps defend your domain from spoofing, and will ensure the proper transmission of your messages. Mail servers that have received mail from your domain use SPF to check the messages that appear to come from your domain are really from your domain.

## Why do we need SPF?

When email was still a relatively new and exotic concept, a few people found ways to benefit from it using forgery. Recipients would get mails from reputed bank domains asking for sensitive data with a sense of urgency and then exploit them. We need SPF to verify that emails sent from a domain are actually coming from the mail server that they claim to be coming from. 

## Benefits of SPF

- A scammer won’t be able to send spoof emails of your domain name. ( Email spoofing is duplicating an email header so that the message appears to have originated from someone or somewhere other than the actual source.)
- Due to no spoofing, your emails will not be discarded in the spam folder which would, in turn, increase your visibility.
- Hence, it increases the overall deliverability of your emails.
- All this boosts your brand reputation. An SPF-protected domain is less tolerant to phishers and is, therefore, less likely to be blacklisted by spam filters.
SPF is beneficial for email marketing but how does every nut and bolt function in this framework?


## How does SPF work?

SPF is an authentication system that coordinates with the mail receiving mail server to check that the incoming email actually originated from a sender who is authorized by the domain’s administrator. 
The method by which an SPF functions is via Simple Mail Transfer Protocol (SMTP). The outgoing mail server makes a connection with the incoming mail server when a message is received.  Your recipient’s server can see your IP address, and the two servers exchange relevant information before your server sends your SMTP mail. In simple words the process is as follows:

**1.** The domain’s administrator publishes a record containing all the mail servers that are allowed to send emails from that particular domain name. This record is called the SPF record.

**2.** The record contains IP addresses that are verified to send emails on behalf of their domains.

**3.** When an incoming email is sensed by the receiving server, the email provider evaluates the IP address of the mail sender with the authorized IP addresses defined in the SPF record.

**4.** If the addresses are not the same, the SPF check fails and the email provider takes the decision to accept, reject or mark the message as spam.

## What is an SPF record?

SPF is a public policy that enables the owner of a domain to list down hosts who are authorized to send mail as delegates of a domain. SPF record can be viewed as a book containing all IP addresses that can send emails using a domain name.
For example, if you send your transactional email from your in-office server and Mailmodo’s email service for your promotional emails, you must approve both of these server addresses as your authorized senders. SPF record can be set up by adding a distinct TXT record that is part of a domain’s DNS (Domain Name Service).


## How to add an SPF record?

The SPF record specifies which mail servers are allowed to send mail to your domain.
Only one TXT record for SPF can be used by a single domain. However, multiple servers and domains that are allowed to send mail to a domain may be listed in the TXT domain record. Follow the given steps to add an SPF record:

**1. Collect IP addresses** 
You might be using various servers to send emails for your domain like your web server, your ISP’s mail server, or any other third-party mail server used to send emails on behalf of your brand. 

**2. How to write TXT format**
After you have set up your SPF record which contains v=spf1, followed by the IP address e.g. v=spf1 ip4:26.27.28.29 . Here ‘v’ is the element and ‘spf1’ is the most common version of SPF that is understood by mail exchanges and ‘ip4:26.27.28.29’ is a random IP address.

**3. Add a new domain name**
Locate the page where the TXT records for your domain are updated. Add whichever new mail server you desire to include and publish it following the above syntax.

**4. Check for errors** 
Within 72 hours, your list will be updated with the new IP addresses. Ask someone who has got a message from your domain to open it and view the full header of the text. Then search the message header for SPF results. If the header indicates that the SPF failed, check the errors in your SPF record.


## How is SPF related to DKIM and DMARC?

SPF, DKIM, and DMARC are all ways to authenticate your mail server. These spam protection methods are becoming increasingly popular and might become a compulsory measure against junk emails someday. Not only that, but confirming your account with these methods will make you a legitimate sender in the eyes of the receiving end server.

DKIM is an acronym for “Domain Keys Identified Mail”. It also goes by the name of “email signing”. DKIM facilitates an encryption key and digital signature that verifies that an email message was not forged or altered which helps to build trust between the sender and receiver servers. It means that no one in between can tamper with any of the emails going from one server to server and that email could be easily recognized from the other end.

DMARC is an acronym for “Domain-based Message Authentication, Reporting, and Conformance”. It’s an email authentication, policy, and reporting protocol that’s actually made with concocting both SPF and DKIM. A DMARC policy applies clear instructions for the message receiver to follow if an email does not pass SPF or DKIM authentication.


## How does SPF help expand your reach?

The two things to keep in mind are ‘delivery rate’ and ‘deliverability.’ They have completely different meanings in email marketing. Your delivery rate can be very high but if your deliverability is poor then your emails are probably landing in the spam folder. The emails have to be delivered in order for email marketing to be successful. The emails are worthless until they actually make it to the user's inbox.

Spammers will try to send unwanted emails, where they can take control of your domain. This will harm your credibility and damage deliverability. You should make it a priority if you have not authenticated your domain. This is how SPF helps take care that your deliverability is high.

- An SPF record will ensure that spammers can’t send emails using your name, hence the chances of your domain getting blacklisted are diminished.
- When email receivers establish trust in your brand due to the use of SPF, your future emails will find a secure entry in their inboxes.
- Some email recipients strictly desire an SPF record and would otherwise mark emails as spam if they don’t compulsorily have one or it might result in email bouncing. 
- Sender Score is a score of every outgoing mail server by using conventional email metrics such as unsubscribers and spam files. SPF majorly helps to increase your Sender Score and inturn helps deliverability.

SPF does look like a one-stop solution for preventing spamming, spoofing, and phishing, but you do wanna take care of a few drawbacks.


## Limitations of SPF

There are a few constraints of the SPF system. They are as follows:
 
- Forwarded mails usually fail the sender policy framework test as they do not contain the original senders’ information and arrears to be a spam message.
- Many domain administrators might not be able to update their SPF record regularly.
- The domain using a third-party email provider must update the SPF record even when the service provider changes its servers, which is just extra work.
- SPF verification is performed on the Mail From (MFrom) domain, which is not visible to the recipient. Hence the recipient system can not completely rely on SPF results.
- SPF authenticates email domains that are buried deep in the message headers and can mislead the end-user. This means that SPF will approve of domain names that might not be clearly visible to the user.

Email providers are aware of these threats and hence try their best to minimize damage as much as possible.


## Conclusion

SPF was designed to protect the envelope sender and it stops spammers from abusing mail systems to trick innocent users. 1 in 6 emails get sent to spam or blocked for your subscribers' inbox altogether. This leads to only 83% conversion. Make sure you are living up to your full potential with Mailmodo.

Learn all about Sender Policy Framework (SPF) and how it helps with better Email Deliverability

The A to Z of Sender Policy Framework (SPF)

It is no secret that one of the most important aspects of business is ‘networking’. One particular way of networking is sending cold emails. In 2020, the rate of exchange for a cold email was 15.11%. A cold email is an initial email sent to a recipient in hopes of gaining value in terms of favor, sales, chance, or any other dual-sided gain. Then, perhaps, sending thousands of emails for your publicity will be your next move. But if you do so, your email address will immediately be blocked. A crucial step in the process to save your emails from getting flagged as spam is to warm up your domain for cold email.

 In this article, we are going to discuss the step-by-step process one needs to follow to warm up domains. Let’s dig into it!

## What is an Email domain warm-up?

The email warm-up is a method for you to develop a reputation and increase the email sending limit for a new email account. The warm-up procedure involves sending email messages from a new email account to a smaller number of people and progressively increasing the number of emails every day.

In 2019, google took more stringent steps from both email sending and receiving sides to detect spam emails. The email service provider gives daily sending limits when a user opens a new email account. Although, a new account can't use it entirely. Ideally, it takes 8-12 weeks to accomplish maximum deliverability. The process of warming up may seem sluggish and repetitive, but it is essential when you want to escape the dreaded spam folder. 

## Why do you need to warm up your domain?

Email domain warm-up is done to signal your service provider that you are not a robot or scammer. It becomes crucial when you are preparing a high-volume cold email campaign from a new account. Given below are the most important reasons you should not overlook the domain warm-up process.

**Avoid spam folder:** Every domain acquires a reputation that ranges from bad to good. The host considers a new account suspicious from the outset. Hence email warm-up service is needed to ensure that emails reach the receivers’ inboxes.

**Email throttling:** Email throttling implies controlling the number of email messages sent to one ISP or remote server at one time. When a large volume of emails is sent at once without domain warm-up, the receiving ISPs often block these messages because they seem to be spam.

**Grey-listing:** As per SMTP protocol, a greylist is a list of email addresses or domain names that are used by a spam filter to detect suspicious emails. If a message comes from the list's address or domain, it will be quarantined i.e. temporarily blocked. You must warm-up your domain to steer clear of greylisting.

**Bounce rates:** When you send emails to email addresses that do not exist, your emails get bounced. Email warm-up tools can help you early on to be in the safe zone and eliminate bouncing.

In a nutcase, domain warm-up will increase your deliverability and open rates while decreasing your bounce rates. 

## A step-by-step guide to email domain warm-up

Domain warm-up demands your time and efforts, as it is a long-term commitment. As you are dedicated to growing your business, email marketing is a cost-effective aid.

**1. Set-up a new domain**

You might want to use your existing company domain to send emails. As it already has a good reputation, it reduces the energy needed for warming it up. Unfortunately, you might encounter problems and burn your primary domain of everyday business. So, register a new domain and prepare it for email outreach

**2. Authenticate your email**

Account authentication is the first thing required with a new email address.
After registering a single domain name for email outreach, simply follow these steps:

- For the RPD (return path domain), develop an SPF (Sender Policy Framework) 
- Create a domain-based message authentication, reporting, and Conformance report ( DMARC) and set monitor policy
- Upgrade IP based Complaint Feedback loop
- Set up MX (Mail Exchange) for your current domain record

**3. Send emails manually**

It is always good to start cautiously till you have gained the email service provider’s trust. 

- You should send 10-20 individual emails from the new email address at the opening juncture. A short-cut tip from Mailmodo is to send them to your relatives and friends. 
- Make sure there is a clear interaction with the initial emails, which will help you increase the number of emails.
- During this time send emails to various email services like Gmail, Yahoo, Outlook, iCloud, Godaddy, etc to broaden your email spectrum.

**4. Cherish responses**

To achieve full deliverability, it is important to generate engagement in your warm-up emails. 

- It is vital to have some daily conversations as it is a continuous 8-12 week operation. Having a faithful response base gives the ISP a hint about your legitimacy. 
- Subscribe to a few newsletters related to your enterprise sector, regularly getting emails is just as critical as sending new emails to warm up. 
- Double the volume of emails every 2 weeks.

**5. Be humane**

The final advice to add as many non-robot-like touches to your emails.

- Don’t send too many emails to the same address at once. Neither should you send email only at a certain time. For example, alternating between mornings and evening and the number of days.
- Avoid fraud-seeming terms in your email copy like donate, free, etc. at the very start. As 69% of people will mark a mail with a long subject line as spam, be smart with your words to attract open clicks.
- Add the unsubscribe link because otherwise, your email looks unprofessional. Your credibility can be adversely impacted by even a single spam report against the new account.
- Personalize your emails by adding as many names as possible. Open rates can be increased by about 22% by adding the name of the recipient in the subject line.

Keep an eye on the process and if the domain warm-up is not meeting your expectations consult an expert. This brings us to the next part.
