“MailerLite's spam blocker feature analyzes email content and offers tips for improvement to help users avoid having their emails flagged as spam by recipients' email filters.”

Patrik K.

Freelancer

“MailerLite knows how important it is for your emails to reach your subscribers, however sometimes they don't make it that far due to spam filters. MailerLite has thus given its users several ways for them to avoid being flagged as spam such as sending emails from a trusted domain that you own, never using purchased email lists and allowing people to unsubscribe. These are just some of the mitigations you can use to avoid being flagged as spam. ”

“I just like the way the Spam Blocker filters harmful emails from reaching my inbox. I checked my spam folder once in a while and this tool is just amazing. In a single day, I had received up to 101 harmful emails which would have bulged my inbox for no reason. This feature has allowed me time to focus on important emails.
