Dirty lists are costing you more than you think

error Bounces damage your sender reputation: High bounce rates trigger spam filters and get your domain flagged. Once your reputation drops, even valid subscribers stop seeing your emails.
trending_down Dirty lists destroy your metrics: Invalid addresses inflate your list size but tank your open rates, click rates, and deliverability scores.
attach_money You're paying your ESP to email dead addresses: Every invalid email on your list costs you money in ESP fees — and gives you nothing back.
auto_delete Lists decay faster than you think: People change jobs, abandon addresses, and domains expire. Lists decay 2-3% per month. Without regular cleaning, your deliverability quietly erodes.

Frequently Asked Questions

Can't find the answer you're looking for? Reach out to our support team.

Does Truelist integrate with my ESP?: Yes. We have native integrations with Mailchimp, ConvertKit, Drip, and HubSpot. Plus Zapier for 5,000+ other tools.
How is Truelist more accurate than other tools?: Enhanced Validation goes beyond standard SMTP checks by cross-referencing multiple data sources. This catches invalid emails on catch-all domains that other tools mark as "unknown."
How often should I clean my email list?: At minimum, monthly. Lists decay 2-3% per month as people change jobs, abandon addresses, and domains expire.
Will cleaning my list hurt my subscriber count?: You'll remove invalid addresses, which lowers your count. But those "subscribers" were never opening your emails anyway. Your real metrics will improve.
What results will I see after cleaning?: Expect lower bounce rates, higher open rates, better click rates, and improved inbox placement. Your ESP deliverability score should improve too.
