How do I avoid landing in spam?

The single biggest lever for inbox placement is correct email authentication on your sending domain — DKIM, DMARC, and SPF.

Inbox placement comes down to three things, in order of impact:

1. Email authentication on your sending domain. DKIM, DMARC, and SPF have to be set up correctly. See How to authenticate email (DKIM, DMARC, SPF).

2. Your domain's sending reputation. New domains start with no reputation; established business domains start strong. If you're sending from a fresh domain, ramp volume gradually — see Warming Up New Email Addresses.

3. The content of the message itself. Spam-trigger words, broken HTML, and overly templated copy all hurt. Our AI-drafted messages avoid the common pitfalls, but a quick scan before you send is worth it.

You may have seen other tools upsell "inbox rotation" or aggressive "warm-up" services. Those are gimmicks for tools that send poorly-authenticated mail at scale. If your authentication is correct and your copy isn't spammy, you don't need them.
