If you are experiencing some of your emails going to spam, this article will talk through the best practices for email deliverability. There are several factors that can affect mailbox providers (such as Google, Yahoo, etc.) decisions to either flag your email as spam, or allow them to arrive at inboxes. Check out the terms and tips below for an understanding of best practices for your emails.
Sending Internal Mail
If you are sending messages to the same domain that the message is coming from (i.e. sending from [email protected] to [email protected]), they may sometimes go to spam. That is because mailbox providers can see that it appears to be receiving a message from itself. This could mean the mailbox provider thinks it is being spoofed, and thus the message will be sent to spam.
Solution: If you must send internal mail to test your messages, you may want to use a free service, like gmail. If you’re sending internal mail outside of testing purpose, the manager of the domain will need to whitelist the IP address of your SMTP provider.
Does the domain you use for sending mail have a DMARC policy? (DMARC stands “Domain-based Message Authentication, Reporting & Conformance”. It is an email authentication, policy, and reporting protocol used to improve protection of a domain from fraudulent emails. You can learn more about DMARC here: https://dmarc.org/)
If your domain uses a DMARC policy but you haven’t verified the domain with your SMTP provider, your messages could be marked as spam.
Solution: Check with your SMTP provider for instructions on how to ensure your messages pass DMARC.
Sending From a Public Domain
If you’re sending messages from a free domain such as gmail.com, yahoo.com, or outlook.com, your messages may end up in spam.
Solution: Send email from a domain that you 0wn which matches your branding. E.g. instead of sending from [email protected], send from [email protected]
