How It Works

Four Steps to Clean CRM Data

Go from connected CRM to verified contact list in minutes, with no exports and no manual uploads.

Step 1

Connect via OAuth

Authorize your CRM account with one click. No API keys, no passwords to store. Tokens refresh automatically.

Step 2

Import Contacts

Browse and select lists, segments, or entire databases. Mailthentic pulls contacts directly, with no CSV exports needed.

Step 3

Verify Every Email

Our 9-point verification engine checks syntax, DNS, MX records, SMTP mailbox existence, disposable domains, and more.

Step 4

Push Results Back

Sync verification statuses, confidence scores, and campaign readiness labels back to your CRM. Segment and suppress automatically.

Why Integrate

Stop Exporting CSVs. Start Verifying Directly.

Manual list exports waste time and introduce data sync errors. Direct CRM integration keeps your pipeline clean in real time.

Eliminate Manual Exports

No more downloading CSVs, cleaning columns, uploading files, and re-importing results. The entire verification cycle happens inside Mailthentic with your CRM connected.

Keep CRM Data Clean

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.

Enterprise-Grade Security

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.

Sync History & Reporting

Track every import and push-back operation with detailed job logs. See per-contact verification status, timestamps, and error details in one place.

Save Hours Every Week

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.

Built for Sales & Marketing Ops

Whether you're a CRM administrator, marketing ops lead, or sales team manager, keep your pipeline data accurate without switching between tools.

Use Cases

Who Uses CRM Email Verification?

Teams across sales, marketing, and operations rely on clean CRM data to protect deliverability and close more deals.

CRM Admins

Ongoing Data Hygiene

FAQ

CRM Integration Questions

Which CRM platforms does Mailthentic integrate with?

Mailthentic integrates natively with Brevo, HubSpot, Salesforce, Mailchimp and PlusVibe. HubSpot, Salesforce and Mailchimp connect with one-click OAuth, while Brevo and PlusVibe connect with your own API key. Do not see your platform? Request it and our team builds the connector for you.

How does the CRM verification workflow work?

Connect your CRM with one-click OAuth, or an API key for Brevo and PlusVibe, then 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 back to your CRM contacts, including verification status, confidence scores, and campaign readiness labels.

Is my CRM data secure during verification?

Yes. Mailthentic uses OAuth 2.0 with token-based authorization, and API keys where a platform requires one, so 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.

Can I push verification results back to my CRM?

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.

Do I need to export CSV files to verify CRM contacts?

No. That's the entire point of the CRM integration. Mailthentic imports contacts directly from your CRM via API, with 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.

How many CRM contacts can I verify at once?

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.
