You need to optimize many of such factors to get your open rates up, and some of the most effective tactics we have discussed below:

To help you out, where it's hard to do email marketing effectively we will discuss 11 effectiveand easy ways to increase your email open rates.

1. Keep your email list clean and updated

It's often advised that you create your email list but keeping that list updated is also crucial.

Over time, your subscribers' behavior is bound to change - they might get a new email id, stop engaging with your emails or shift their interests and preferences.

Ensure that you periodically filter out such inactive and invalid addresses and keep only the most active and relevant subscribers.

2. Segment your email list

So, you have cleaned out your inactive subscribers but let's not stop there. Analyze your subscriber's data and figure out the best way to create segments out of your email list.

Some of the common ways to segment your email subscribers are:

  • Demographic: Age, gender, ethnicity, occupation
  • Geography: Country, city, Pincode
  • Psychographic: values, hobbies, interests
  • Behavioral: Past interactions and engagement
  • Lifecycle stage: New customers, existing customers, loyal customers
  • Funnel stage: Top, Middle, or bottom

Once you segment the list, you can tailor your email subject line and preheader that resonate with that particular segment.

To know in detail, you can read our email list segmentation guide.

3. Use double opt-in

Verifying email addresses by asking them to confirm their email address is a helpful tactic to maintain a good quality contact list. It will also help you segment users based on who confirmed their email address and who didn't.

With double opt-in, you can ensure that only the most interested people are becoming a part of your email marketing journey as they will be prompted to check out your emails and get you higher opens.

4. Write a compelling subject line

The subject line is your ticket to create a great first impression and compel the reader to click on your email. In a crowded inbox, your subject line is what will make you stand out and connect with your audience.

A good subject line is relevant and compelling and gives the reader a strong reason to open an email.

Here's great advice from Chase Dimond on writing subject lines to get higher opens:

Here are a few more best practices to create a compelling subject line:

  • Keep it within the standard character limit for both desktop and mobile.
  • Make it personal by adding the recipient's name, date of birth, or other relevant information.
  • Keep it descriptive and clear. Avoid being clever.
  • Use emojis to showcase creativity and say more using fewer words.
  • Add numbers to break through the common pattern.
  • Use jokes or humor to hook the reader.
  • Leverage trending topics and incorporate them into an intriguing subject line.
  • Avoid any inappropriate or offensive words.
  • Avoid spam trigger words like Cheap, 100% sale, Hurry Up, etc.

5. Write an enticing preheader text

Preheader text is your ally to get you a higher open along with the subject line. The preheader text is the right place to give a little sneak peek into your email content and encourage them to click.

Here are some best practices for the preheader text you should follow:

  • Write a brief line or add a question that would arouse the reader's curiosity
  • Personalize it using the recipient's name, date of birth, mentioning past activity, etc.
  • Use emojis to create an enticing story.
  • Create a sense of urgency like a limited-time offer, coupon deals, etc.

6. Build brand recognition with BIMI

Brand Indicators for Message Identification (BIMI) is a standard that adds a little photo of the brand or sender next to the sender's name.

Here's an example of what BIMI looks like in the recipient's inbox ๐Ÿ‘‡๐Ÿผ

Adding a logo helps the recipient instantly associate the email with your brand, even before they read the subject line. It's a great way to stand out in users' crowded inboxes. It helps build brand recognition and trust and gets the recipient to open the email.

7. Optimize subject line for mobile users

Mobile email will account for 26 to 78% of email opens, depending on your target audience, product, and email type. - eMailmonday, 2021.

But, you should also analyze your data to figure out which devices your subscribers are using to open and interact with your emails.

As mobile screens are smaller, the character display count is also less than desktop devices. Mailchimp recommends using no more than 9 words and 60 characters to make the subject line look compelling on mobile devices.

8. Decide the best time to send an email

Timing is a significant factor that can have a huge impact on your email open rates.

The best time to send an email is usually decided by several factors, including geography & demography of your target audience, holidays, type of emails, etc.

For example, if your target audience is students, the best time would be in the evening or weekend as these people are most active during that time. Getting familiar with their timezone is essential if your target users are across different countries.

There are different ways to find the timings, and one of the most common is to A/B test your timings. Send an email at different timings over some time and analyze the results for each version.

Besides, you can also look into your subscriber's past behavior using analytics and assess the activity level on different days and times.

9. Keep an eye out for spam filters

Mailboxes are getting more strict with their spam filtering operations and will hurt your open rates if your emails are caught in these deadly spam filters.

Once your email gets hit by spam filters, they get landed in spam folders impacting your IP's reputation and thus, lowering your email deliverability. Lower email deliverability is directly proportional to lower open rates.

So, you should follow these practices to avoid these filters:

  • Use a clear and recognizable sender name.
  • Don't use deceptive email subject lines.
  • Send emails only to those who have opted-in.
  • Verify the sender domain before sending emails.
  • Avoid spam trigger words like Cheap, jackpot, 100% free, and profits in your email subject line, preheader, and email copy.

10. A/B test your subject line and preheader text

You can make all the optimization by following the right practices but still don't get the desired open rates. It's disheartening to see your investment and time go in vain.

A great way to resolve such drawbacks is to test your emails via A/B testing. A/B testing helps you eliminate the guesswork, and you can get data backed up results to make the changes.

Here's how it works: Create two emails with slightly different subject lines; one will be version A and the other version B. Then, send them to two different segments at the same time. Run the test until you get enough data to draw insights.

This approach will help you identify which subject line resonates most with your audience and can use it to send future campaigns.

Apart from the subject line, you can test different variables:

  • Preheader text copy
  • Day and time of sending email
  • Profile image

11. Be relevant and always provide value

For building long-term relationships with your customers, you need to provide value so that the customer can connect with your brand and become your loyal customers.

In some scenarios, your subscribers might not buy the product themselves, but they can recommend your product to their family and friends, which will result in the growth of your business in the long run.

Every subject line and preheader text your write must offer value and give a strong reason why your email is worth their time.
