What Could Be Causing This?
Sending Domain Not Authenticated in ActiveCampaign
Most CommonActiveCampaign requires SPF/DKIM authentication. Unauthenticated domains trigger spam filters immediately.
How to confirm:
In ActiveCampaign Admin > Settings > Sending Domain, verify domain shows green checkmarks for SPF and DKIM.
ActiveCampaign IP Reputation Issues
Most CommonActiveCampaign shared IPs can suffer reputation damage. This is invisible until reputation drops.
How to confirm:
Check Google Postmaster Tools for domain reputation trends. Contact ActiveCampaign support if reputation is low.
High Bounce Rate Damaging ActiveCampaign Reputation
CommonBounces above 3% signal poor list quality to ISPs, triggering spam filtering.
How to confirm:
In ActiveCampaign Reports, check bounce rate for recent sends.

Step 1: Authenticate Your Domain in ActiveCampaign
- In ActiveCampaign, go to Admin > Settings > Sending Domain
- Add your domain and verify you own it
- ActiveCampaign provides SPF and DKIM records — publish them in your DNS
- Wait for DNS propagation (5 min to 48 hours)
- ActiveCampaign confirms when authentication is complete
ActiveCampaign-Specific Note:
ActiveCampaign's domain verification process is automated and usually completes within 24 hours.
Step 2: Clean Your ActiveCampaign List
- In ActiveCampaign, export bounced contacts
- Remove all hard bounces and unengaged subscribers
- Delete any contacts with multiple bounces
- After cleaning, bounce rate should drop below 2%
ActiveCampaign-Specific Note:
ActiveCampaign tracks bounce metrics per campaign — use these to identify problem addresses.
Step 3: Warm Up Your ActiveCampaign Sending
- If reputation is low, reduce sending volume by 50%
- Focus sends to your most engaged subscribers for 3-5 days
- Gradually increase volume as reputation recovers
- Monitor Google Postmaster Tools daily
ActiveCampaign-Specific Note:
ActiveCampaign doesn't have built-in warmup tools — manage volume manually in your automation settings.
