Does ColdSend have an API?

Last updated on Sep 27, 2025

Not yet, but it's on our roadmap. Expected release date: Early November 2025.

In the meantime, we have ColdInbox API. It doesn't work like ColdSend (i.e., requires warmups) since it is just standard SMTP (Sendgrid wrapper). If you have programmatic email use-cases, feel free to check ColdInbox out. Otherwise, wait till ColdSend API is released.

To get started with ColdInbox, email us at hello@coldsend.pro with the subject line, "ColdInbox API" and the email with which you want to register with us. We will send over your API token. Then you can follow this documentation to create inboxes, manage replies, send emails etc.
