Integration

Verify your AWeber audience before you send

AWeber's own import guidance asks that subscribers have been collected or contacted within the last six months, since older contacts carry a higher bounce risk and hurt deliverability. Running a list through Bounceless before you reimport it puts that guidance into practice: dead mailboxes and disposable addresses get caught as rows in a CSV, not as bounces AWeber has to process against your account after the fact.

How it works

[01]Export your AWeber listOn the Subscribers page, optionally use the filter menu to narrow the list, then click Export CSV (top right of the subscriber list) to download the contacts you want to verify.
[02]Upload the CSV to BouncelessCreate a new bulk verification job in the Bounceless dashboard and upload the exported CSV. Every address returns a confidence level, reason codes, and a Pre-Send Decision.
[03]Download the verified resultsOnce the job finishes, download the results file. Addresses are grouped by Pre-Send Decision: send, review, or suppress.
[04]Reimport the clean list into AWeberClick Subscribers, then Add Subscribers, then Import multiple. Confirm the destination Active List, upload the send-decision CSV, map the email field, and choose Update existing subscribers only or Add new subscribers and update existing so you do not create duplicates.
[05]Remove the addresses Bounceless flagged as invalidOpen the Bulk Unsubscribe page under Subscriber Tools, paste the suppress-decision addresses into the Emails field, check Block these subscribers, and click Unsubscribe so they cannot resubscribe or receive a future send.

When to run it

Pre-import scrub for cold or purchased listsAWeber recommends importing only subscribers collected or contacted in the last six months. Verify an aging or purchased list with Bounceless first so only addresses that pass go through the import review.
List merge cleanupWhen you consolidate subscribers from another platform or an older AWeber list, verify the combined export before reimporting so the merged list does not inherit dead addresses from either side.
Recurring suppression hygieneRe-verify an active list on a schedule and run any suppress-decision addresses through Bulk Unsubscribe and Block, instead of waiting for AWeber to process the bounces one campaign at a time.

Common questions

Does this integration require connecting my AWeber account through the API?

No. The workflow is CSV-based: export from AWeber, verify in Bounceless, reimport the clean segment. Your AWeber login and any API credentials stay out of it entirely. AWeber's own developer docs describe an OAuth 2 authorization flow for teams that want a fully automated, push-based sync instead, but that is a separate, developer-level setup and not required for the CSV workflow above.

Will reimporting the verified CSV create duplicate subscribers in AWeber?

Not if you use AWeber's own import controls. During Import multiple, choose Update existing subscribers only or Add new subscribers and update existing, and AWeber matches incoming rows to existing subscribers by the mapped email field rather than adding a second copy of contacts who are already on the list.

How is this different from AWeber's suppression list and unsubscribe tools?

AWeber's suppression and unsubscribe tools act after a subscriber has already bounced, complained, or opted out, and there is no documented bulk hard-delete for active subscribers outside those mechanics. Bounceless verifies addresses before you send or reimport, so a mailbox that will bounce is caught up front; Bulk Unsubscribe and Block is then the closest AWeber-native way to act on what Bounceless flags.
