Our 9-point verification engine checks syntax, DNS, MX records, SMTP mailbox existence, disposable domains, and more.
Sync verification statuses, confidence scores, and campaign readiness labels back to your CRM. Segment and suppress automatically.
Manual list exports waste time and introduce data sync errors. Direct CRM integration keeps your pipeline clean in real time.
No more downloading CSVs, cleaning columns, uploading files, and re-importing results. The entire verification cycle happens inside Mailthentic with your CRM connected.
Verification results sync back to your CRM with status labels like Safe, Likely Safe, Caution, and Do Not Send. Use these to build suppression lists and targeted segments.
OAuth 2.0 authorization means no passwords are stored. Tokens refresh automatically, and all data is encrypted in transit. Contact data is purged after processing.
Track every import and push-back operation with detailed job logs. See per-contact verification status, timestamps, and error details in one place.
Teams that verify CRM contacts manually spend 3-5 hours per week on data hygiene. Direct integration reduces that to minutes with automated import and push-back.
Whether you're a CRM administrator, marketing ops lead, or sales team manager — keep your pipeline data accurate without switching between tools.

Mailthentic currently integrates with HubSpot, Salesforce, and Mailchimp. All three use secure OAuth 2.0 connections — no API keys to manage. We're actively exploring additional CRM and marketing platform integrations.
Connect your CRM via one-click OAuth, browse and select contact lists to import, then Mailthentic verifies every email using our 9-point verification engine (syntax, DNS, MX, SMTP mailbox, disposable detection, and more). Once complete, push results — including verification status, confidence scores, and campaign readiness labels — back to your CRM contacts.
Yes. Mailthentic uses OAuth 2.0 with token-based authorization — no CRM passwords are ever stored. All data transfers are encrypted via HTTPS, and imported contact data is automatically purged after processing completes. We never share or resell your contact data.
Absolutely. After verification, you can push status labels (Safe, Likely Safe, Caution, Do Not Send), confidence scores, and custom tags back to your CRM contacts. Use these to build suppression lists, segment audiences, or trigger workflow automations in your CRM.
No. That's the entire point of the CRM integration. Mailthentic imports contacts directly from your CRM via API — no CSV exports, manual uploads, or column mapping required. The entire flow happens within the Mailthentic dashboard. If you prefer CSV workflows, our bulk email verifier supports that too.
There's no hard limit on list size. Mailthentic processes CRM imports using the same parallel verification engine as our bulk verifier, handling thousands of contacts per minute. Each verified email consumes one credit from your account balance.
