What Could Be Causing This?

Sending Domain Not Authenticated in ActiveCampaign

Most Common
InboxEagle Detects This ✓

ActiveCampaign 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 Common
InboxEagle Detects This ✓

ActiveCampaign 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

Common
InboxEagle Detects This ✓

Bounces above 3% signal poor list quality to ISPs, triggering spam filtering.

How to confirm:

In ActiveCampaign Reports, check bounce rate for recent sends.

Fix Playbook

Step 1: Authenticate Your Domain in ActiveCampaign

HoursImpact: High
  1. In ActiveCampaign, go to Admin > Settings > Sending Domain
  2. Add your domain and verify you own it
  3. ActiveCampaign provides SPF and DKIM records — publish them in your DNS
  4. Wait for DNS propagation (5 min to 48 hours)
  5. 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

HoursImpact: High
  1. In ActiveCampaign, export bounced contacts
  2. Remove all hard bounces and unengaged subscribers
  3. Delete any contacts with multiple bounces
  4. 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

DaysImpact: Medium
  1. If reputation is low, reduce sending volume by 50%
  2. Focus sends to your most engaged subscribers for 3-5 days
  3. Gradually increase volume as reputation recovers
  4. Monitor Google Postmaster Tools daily

ActiveCampaign-Specific Note:

ActiveCampaign doesn't have built-in warmup tools — manage volume manually in your automation settings.
