SendGrid reviews accounts that appear to have irregular activity, which may be the result of technical problems, blocking by ISPs, or poor email sending practices. If you receive a warning, suspension, deactivation, or ban notice from SendGrid, it is essential that you promptly follow the instructions in the email notice to avoid a further interruption in service. The impacts on your account are explained below, and range in severity based on the factors which initiated the review:
Warning: The account maintains all of its functionality for the duration of the warning. However if the issue our team identified in the warning email has not been addressed within 48 hours the account will be suspended.
Suspension: SendGrid will accept and queue mail while the account is suspended, but the mail will not be delivered until the issue is resolved. Mail will be queued for up to 72 hours. If the issue that caused the suspension has not been addressed within 48 hours, the account will proceed to the next stage in the review process -- deactivation.
Deactivation: SendGrid will not accept mail while an account is deactivated. Once deactivated, any undelivered mail that has been queued on SendGrid’s systems will be deleted. While the account is deactivated, click and open tracking links will be disabled. If the issue has not been resolved within 48 hours the account will proceed to the next stage of review and be banned.
Ban: When an account is banned, it is permanently cancelled. Access to the account is blocked and no further requests to our system will be accepted. A banned account is not allowed back on SendGrid in the future. If the account had dedicated IPs they will be removed. Sub-users will also be banned.
Reactivation: If the issues which flagged your account are resolved, SendGrid will reactivate the service, at which point the account will be restored.
