How does the Yahoo spam filter work?

Yahoo mail’s spam filter looks for specific signals in emails such as a blacklisted IP, poor domain reputation, user complaints. If it finds any of these signals in emails, it’ll put them into recipients’ spam folders.

How to pass through the Yahoo spam filter?

You’re probably aware of the apparent things like maintaining a good domain reputation and getting your customers’ permission. So let’s learn about things you can do to improve Yahoo mail deliverability specifically.

Check if Yahoo blacklisted your sender IP

You won’t be able to send emails in the first place if Yahoo has blacklisted your sender IP. Instead, you’ll just receive an error message after sending your emails.

To resolve this issue, first, you must check if you are listed in The Spamhaus Block List and if you’re in their list, you must delist yourself. Since Yahoo uses Spamhaus to identify spam sources, it’ll treat you as spam as long as you’re on Spamhaus’s list. So you can avoid being backlisted by Yahoo if you delist yourself from Spamhaus.

Use Yahoo spam checkers

You can use Glockapps’s spam checker to see where your emails are delivered in Yahoo mail, Gmail, Outlook, and other ISPs. It’ll show you whether your emails are delivered in the spam folder, inbox, updates, or other subfolders.

It’ll give your email an overall spam score after running it through Google Spam Filter, SpamAssassin, Barracuda, and Mimecast. The tool will also give you ways to change your content to improve your email deliverability.

Ask users to add you to their contact list

If someone makes an effort to add you to their contact list, it means you are important to them, right? That’s what Yahoo will think. So ask your users to add your email address to their contact list. You can visit Yahoo’s help page to learn how to add a contact from an email.

Send relevant content

Having an excellent domain reputation, a non-blacklisted IP is great. But your users will still mark you as spam if you send them irrelevant content. A person wouldn’t like to receive emails about political debates if he is not interested in politics. So if you still send political content to uninterested users, they’ll mark you as spam. This will signal to Yahoo that you’re not sending helpful content. Thus it’ll put your future emails in the spam folder.

So ask your audience about what they want and only send relevant content. Doing so will improve your open rates and keep you away from the spam folder.

Don’t mix up your sending frequency

Some users may choose to opt-in only to your weekly email list. You should respect that decision and only send them your weekly emails. If you send daily emails to your weekly list, you’re likely to be marked as spam. Send emails to your users when they want you to.

Wrapping up

Nobody wants to end up in the spam folder, and I’m sure you don’t want it too. You can safeguard many of your emails by checking for a blacklisted IP, using spam checkers, sending relevant content, and following other tips mentioned in the guide.
