AWeber deliverability: beyond the authentication setup

AWeber deliverability problems that persist after authentication is confirmed usually come from one of three places: list hygiene, content patterns that trip filters, or shared sending infrastructure reputation. Authentication is necessary but not sufficient.

Confirm authentication is fully live, not just set up

AWeber's domain authentication wizard generates SPF and DKIM records - copy the exact DKIM selector value from AWeber's settings screen at the time you configure it, since this is account-specific. Verify propagation directly rather than relying on the setup wizard's completion message:

dig TXT yourdomain.com +short
dig TXT _dmarc.yourdomain.com +short

If DMARC is not yet published, add one at p=none first to monitor alignment before moving to a stricter enforcement policy - jumping straight to p=reject without confirming SPF and DKIM pass consistently risks blocking your own legitimate mail.

List hygiene, specifically around import history

AWeber accounts with a long sending history often accumulate list segments imported years ago from various sources - old opt-ins, migrated lists from a previous ESP, conference sign-ups. Contacts from older imports are statistically less likely to still be engaged, and a domain sending heavily to a list with a long tail of old, unengaged contacts carries more reputation risk than a smaller, actively-engaged one.

Content patterns worth checking

If authentication and list hygiene both check out, review content: heavy use of all-caps or excessive exclamation points, link-shortener domains, or display names that don't match the sending domain (a common pattern when brand names differ from domain names). None of these alone will sink deliverability with strong authentication and reputation, but they tip borderline sends toward spam.

Shared infrastructure reputation

AWeber's standard sending tier, like most ESPs in this tier, uses shared IP infrastructure for most accounts. An unexplained placement drop with no corresponding change in your own sending practices is sometimes attributable to another sender on the same shared pool - worth checking before assuming the cause is internal.

What AWeber's dashboard doesn't show

Open and click rates in AWeber's reporting are useful for relative trend-watching but are not deliverability metrics - Apple Mail Privacy Protection inflates opens for Apple Mail recipients regardless of actual engagement, and delivered status reflects a successful SMTP handoff, not inbox placement. A message landing in spam still shows as delivered. Actual placement requires sending to seed addresses across major providers and checking the folder directly.

DMARC as an early-warning system on an established domain

For an account with years of sending history, moving DMARC from p=none to p=quarantine - once alignment has been confirmed stable - gives visibility into authentication failures that might otherwise go unnoticed on a domain that's been "working fine" for a long time. Long-running accounts sometimes accumulate secondary senders (a transactional tool, a form notification service) using the same domain without proper SPF inclusion, and a stricter DMARC policy surfaces those gaps through aggregate reports rather than leaving them to degrade reputation silently over months of unnoticed failed alignment.

Auditing an older account's list history

If you've been sending through AWeber for several years, it's worth a one-time audit of where every current list segment originally came from - which imports, which sign-up forms, which point in the account's history. Segments with unclear or unverifiable opt-in history are the ones most worth suppressing or re-permissioning first, since they carry the highest uncertainty about whether recipients actually still want this mail, regardless of how long ago they were added or how reliable the engagement numbers for that segment look today.

What not to do

Do not resend to a segment immediately after a bounce or complaint spike without first identifying the cause. Continuing to mail into a damaged segment accelerates reputation decline rather than recovering it.

Do not assume an older, established AWeber account is immune to reputation problems. Account age does not protect against the effects of a stale list or a content pattern that starts tripping filters - reputation is a current, ongoing measurement, not a one-time qualification, and a long sending history can just as easily mean a long tail of accumulated list hygiene debt nobody has gone back to clean up.

Where MailPilot fits

MailPilot does not integrate with AWeber. For the sending domain or a related mailbox reachable over OAuth (Gmail, Outlook) or SMTP/IMAP (SendGrid, Amazon SES, Mailgun, Postmark, custom SMTP), MailPilot verifies SPF/DKIM/DMARC against the live DNS record, tracks daily reputation per mailbox, and runs seed-inbox placement tests - visibility that goes beyond what AWeber's own authentication wizard and campaign reports provide.
