Truelist adds recurring email validation to automate list hygiene

Truelist has launched Recurring Email Validation, a new feature that automatically re-checks marketing lists weekly, biweekly or monthly to catch bad addresses before they hurt deliverability. The rollout aims to reduce manual list-cleanup work for teams using email platforms like Mailchimp, Klaviyo and HubSpot.

Why it matters: - Marketing email lists naturally decay by 2%-3% each month as people change jobs, abandon inboxes and domains go offline. - A list that looks clean today can be meaningfully degraded within 90 days. - Early detection of bad addresses can help protect sender reputation and deliverability.

What happened: - Truelist announced Recurring Email Validation on June 22, 2026. - The feature automatically validates a customer’s entire email list on a schedule the customer chooses: weekly, biweekly or monthly. - The company says the goal is to keep marketing lists clean without manual effort.

The details: - Customers connect an email service provider once through OAuth, and Truelist then pulls contact lists automatically. - Validation runs in the background, removing the need to export CSV files, upload them to another tool and re-import results. - Each scan checks for newly bounced or deactivated mailboxes, expired or changed MX records, recycled spam traps, role-based addresses that changed owners, newly flagged disposable email providers and catch-all domains that stopped accepting mail. - The feature works with Mailchimp, Klaviyo, HubSpot, ConvertKit, ActiveCampaign and Constant Contact. - Truelist also offers the feature through its API for teams that want to build their own recurring schedule. - After each run, customers can automatically suppress invalid addresses in their ESP, tag them for manual review, or do both. - Customers also get a summary report showing what was found and what action was taken. - The feature is included on all Truelist plans under flat monthly pricing with unlimited validations. - Setup takes under two minutes and does not require a credit card. - More information is available in Truelist’s feature page.

Between the lines: - The launch pushes Truelist from one-time list cleaning toward ongoing list maintenance. - Automatic re-validation may be most useful for teams running large or fast-changing email programs. - The unlimited-validation pricing model removes a common barrier to frequent checks.

What's next: - Customers can begin using recurring validation immediately on supported plans. - Teams that need custom workflows can build recurring schedules through the Truelist API. - Truelist’s social updates are available on X.

The bottom line: - Truelist is betting that automated, scheduled validation will be easier to adopt than manual list cleanup and will help marketers protect deliverability before problems spread.
