Catch-all addresses: a major risk to deliverability
Sending emails to 'catch-all' addresses is a risky bet. These servers accept all messages by default, often masking full mailboxes or inactive accounts. The result: increased bounce rates that immediately degrade your sender reputation score.
Main negative impacts:
Declining sender reputation
ISPs monitor your bounce rates. Too many bounces and your emails will consistently end up in spam folders.
Loss of business opportunities
When your messages are blocked by antispam filters, your prospects never receive your critical communications.
Blacklisting risk
Poor list hygiene can lead to your domain being blacklisted, paralyzing your professional correspondence.
Swiftask's Catch-all Verifier connector analyzes your lists beforehand. It identifies risky addresses, allowing you to clean your data before even launching your campaign.
BEFORE / AFTER

Without Swiftask
You upload a raw list into your email tool. You send thousands of emails to unverified catch-all addresses. The bounce rate skyrockets, your domain is flagged by filters, and your open rates drop drastically.
With Swiftask + Catch-all Verifier
Before sending, Swiftask scans your addresses. It isolates suspicious catch-alls. You choose to exclude them or process them separately. Your reputation remains intact, and your emails reach the primary inbox.
