If you have noticed that your emails are going to spam for various receivers, this can indicate a many reasons why this has happened: 

  • your content is being detected as spam like;
  • you're not using a reliable method to send emails;
  • many other reasons that are described in this article.

We will guide you through on how you can prevent your emails from going to spam inbox:

Option 1

The easiest option - for the recipient himself to remove the spam mark once you sent (accidentally or intentionally) a message. In this case, the recipient just needs to click Not spam on all emails from you - and for him they will never get to spam inbox again.

Option 2

The next most common cause is not a reliable method of sending a message. 

The phpmail() function is very popular, but it is already outdated due to insufficient security. This feature is enabled on shared hosting, you can use it for one-time sending messages, but for regular correspondence you need to switch from phpmail() to SMTP. This is a much more reliable way to send emails, which will improve the delivery of your messages.

An additional nice bonus when switching to SMTP : if the message is sent via phpmail() then the recipients will see it this way:

When sending via SMTP, only your domain will be there, which increases the trust for the recipients 🚀 

If your site is WordPress, you can configure SMTP settings following this guide .

Option 3 

All modern mail services have an additional verification of the sender:
is it from this address, this domain, that this letter was sent from? This check takes time and the message may be marked as spam if it does not pass. 

To help the domain pass such checks, you just need to add 2 TXT records. 

SPF record

For domains purchased at Hostinger (or directed via NS records), this entry is added by default. You can also add it manually if you have no TXT records, you will need to go to the DNS zone editor :

And find TXT (Text). If there are no records, you can add SPF record in one click on the same page:

DKIM Record

To automatically add a DKIM record, go to Mail Service Control

Turn on the last switch ( Manage DKIM service ) and click update

Done, you can find both entries in the TXT section in your DNS zone:
