3

Set Verification Rules

Configure automatic verification for new contacts added via API, CSV upload, or form integration. Set suppression rules to automatically block invalid addresses from future sends.

Frequently Asked Questions

How does Cleanlist improve SendGrid deliverability?

+

Cleanlist verifies every email address before it reaches SendGrid using a triple verification process. Invalid, disposable, and role-based addresses are flagged and can be automatically added to suppression groups, preventing bounces that would damage your sender reputation and IP health.

Can Cleanlist sync with SendGrid suppression groups?

+

Yes. Cleanlist can automatically add verified-invalid email addresses to your SendGrid suppression groups. This ensures that known bad addresses are blocked from future campaigns without manual list management.

Does this work with SendGrid transactional and marketing email?

+

Yes. Cleanlist verification works for both SendGrid Marketing Campaigns contacts and transactional email recipients. You can verify addresses at import time for marketing or in real time via webhook for transactional flows.

How many SendGrid contacts can I verify?

+

There is no limit on the number of contacts you can verify. Bulk verification processes at roughly 1,000 addresses per minute, and real-time webhook verification returns results in under two seconds per address. Volume depends on your Cleanlist plan credits.
