Drip SendHow to avoid spam filters in personal outreach
Spam placement is rarely about one "bad word." It is mostly about trust signals: authentication, list quality, consistency, and recipient engagement.
Anti-spam foundation checklist
- SPF, DKIM, DMARC all configured and valid.
- Consistent sender name and from address.
- Clean list with no purchased or stale records.
- Reasonable daily/hourly sending caps.
Copy signals that help
- Short, clear subject lines.
- Plain text style formatting.
- Specific relevance for each recipient.
- One clear CTA, no hype-heavy claims.
Behavior signals that hurt
- Sudden volume spikes.
- Ignoring unsubscribe or reply signals.
- Repeated sends to low-quality addresses.
- Running long automated sequences without review.
Fast recovery plan
- Reduce sending volume immediately.
- Pause weak sequences.
- Trim problematic list segments.
- Re-test with small batches.
