But…why would my emails go to spam anyway?

There could be multiple reasons why your emails can go to spam, such as:

Your content is spammy

Your content contains trigger words, misleading subject lines, or poor formatting.

No email authentication

You’ve missed SPF, DKIM, or DMARC records, so email services can’t authenticate you.

You have a bad sender reputation

There are spam complaints and high bounce rates on the emails you’ve sent so far.

There’s low engagement

You have poor open/click rates or you’re sending to inactive users.

So…how do I fix this and have my emails land in inbox?

You can stop your emails from going to the junk or spam folder through several methods. However, the best way is to go for an email warmup (especially if you’re starting fresh or trying to recover from damage). We’ll send automated warmup emails that mimic real conversations, gradually build trust, and detect if your emails are landing in spam.

We realized other tools in the market fixed different parts of our deliverability rate, which we then had to duct-tape together. We went with Maxify because everything is solved in one place. Plus, they paired us with a deliverability consultant who’s just a call away, ensuring our emails increase sales not spam.

Honestly surprised—within the first week their consultants jumped on a call, got us off the blacklist, and boosted our Google Postmaster reputation. Way beyond what we expected.
