How do I disconnect or revoke the SendGrid integration?

Last updated May 20, 2026Integrations

Removing the SendGrid integration from Valid Email Checker is a two-step process for full hygiene. Step one: delete the connection on our side. Step two: revoke the API key inside SendGrid. Step one stops VEC from accessing SendGrid; step two ensures the key cannot be reused elsewhere.

Step 1: delete the connection in VEC

Sign into VEC and open Integrations.
Find the SendGrid row in Connected Integrations.
Click the three-dot row menu and pick Delete.
Confirm in the modal.
The SendGrid entry disappears from the table immediately.

Deleting the connection also clears the sync history attached to it. Past verification jobs remain in your Uploads & Results page as independent records.

Step 2: revoke the API key in SendGrid

Sign into SendGrid.
Open Settings → API Keys in the SendGrid sidebar.
Find the API key you used to connect to Valid Email Checker (it likely starts with SG.).
Click the action menu next to the key and pick Delete. SendGrid invalidates the value immediately.

Why revoke separately

Deleting on our side removes our stored copy of the key. The key string itself remains a valid SendGrid credential unless you delete it there. SendGrid also surfaces per-key activity logs, which makes it easy to confirm VEC is no longer calling the API.

Impact on transactional sending

Disconnecting the SendGrid integration only removes VEC access to your Marketing Contacts. Transactional sending (the Mail Send API) is independent and continues to work. Your application code uses its own dedicated key for transactional sending — assuming you followed SendGrid best practices and did not reuse the same key for both Marketing and Mail Send. If the same key was used for both, regenerating breaks your transactional code.

What happens to running verifications?

A verification mid-import keeps running with the cached credentials. New sync attempts fail immediately until you reconnect.

Reconnecting later

Reconnect by going to Integrations → Connect Integration → SendGrid and pasting a fresh API key (Marketing-scoped, see the SendGrid integration guide for scope details). The new connection is unrelated to the deleted one. If you previously named the connection something distinctive (recommended in multi-account workflows), reuse the name for team-facing consistency.

Team-member-created connections

Connections created by team members show a Users badge in the Provider column. Owners can delete any connection; team members can only delete connections they themselves created.
