Reduce the risk of email landing in spam
Last verified 2026-08-17
A delivered event means the receiving mail system accepted the message. It does not prove that the message reached the primary inbox, and no outreach platform can guarantee inbox placement.
Check the foundations first
- Confirm SPF, DKIM, and DMARC for the exact sending domain, and fix authentication failures before increasing volume.
- Use a real individual sender identity, a complete signature, and a mailbox that can receive replies.
- Remove invalid, opted-out, role-based, and repeatedly bouncing addresses before the next send.
- Keep volume steady and conservative. Pause after a sudden bounce or provider-error increase instead of trying to send through it.
Review the message and the audience
- Send only to a relevant business audience with a clear, supportable reason for contact.
- Avoid misleading subjects, unnecessary tracking links, link shorteners, large attachments, and repeated sales-heavy wording.
- Make opting out simple and honor every suppression immediately across future Kampaigns.
- Compare provider-confirmed delivery, bounces, replies, and failures over a meaningful sample. Treat inbox placement as unknown unless the receiving side confirms it.
If a healthy mailbox suddenly performs badly, stop new sends, inspect authentication and recent list or copy changes, and contact the mailbox provider when its own logs show a reputation or policy restriction.
