My emails are landing in spam — first checks

Spam placement is almost always a mix of missing authentication, a cold domain, unverified lists or overly promotional copy.

Fix in this order

Authentication and warmup first — they account for most cases. Then list quality, then copy.

Volume

Cap a healthy warmed mailbox at 30 to 50 emails per day. Scale by adding mailboxes, never by pushing one mailbox harder.

Copy signals

Keep the first email plain text with at most one link. Multiple links, tracking pixels and image-heavy HTML all add risk.

Give it time

Authentication changes propagate within hours, but sender reputation is cumulative — expect one to three weeks of clean sending before inbox placement fully recovers.
