SendGrid

Connect SendGrid with emailcheckerr to verify every email address before it hits your campaigns. Cloud-based email delivery for transactional and marketing communications. Pair it with our SMTP-grade verification to keep your sender reputation healthy, drive higher open rates, and protect your inbox placement.

Whether you import lists from SendGrid for a one-off cleanup or pipe new sign-ups through emailcheckerr in real time, you get the same disposable / role / accept-all detection, deep MX validation, and quality scoring used by enterprise teams — at a fraction of the cost.

How it works

Verify before SendGrid sends

Hit the emailcheckerr API right before submitting a transactional email to SendGrid. Skip the send for any address marked undeliverable.

Drop bounces preemptively

Most hard bounces in SendGrid can be prevented by a sub-second emailcheckerr check at sign-up or order confirmation time. Your bounce rate stays low, your IP reputation stays clean.

Reconcile bulk sends

For one-off broadcasts, run the recipient list through emailcheckerr first and feed only deliverable addresses to SendGrid.
