| Action | Why it helps |
|---|---|
| Authenticate your domain | Builds sender trust |
| Use clean recipient data | Reduces bounces |
| Honor suppressions | Avoids repeated bad sends |
| Send expected messages | Improves engagement and trust |
Start with domain authentication
SPF, DKIM, and DMARC tell receiving servers that your email is authorized and aligned with your domain.
Protect your reputation
Do not send to scraped lists, old lists, or people who did not expect your email. Bounces and complaints are strong negative signals.
Use ZidiMail signals
Track delivered, bounced, complained, opened, and clicked events. Use suppressions to avoid repeatedly emailing recipients who should not receive mail.
