A new API endpoint is available (email/batch), which allows you to send or schedule a batch of up to 1,000 emails. Further details can be seen in our API documentation.

We’ve introduced a new optional parameter, "fastaccept", to our email sending API that can significantly improve sending performance. We’ll be making this the default setting in the future. See the API documentation for more detail.

A new schedule property has been added to our /email/send and /email/mime API endpoints. You can now schedule emails to be sent up to 3 days in advance.

When you use the schedule property, the endpoint will return a schedule_id instead of an email_id. This ID can be used to track the delivery of your email via webhooks. The email will also receive a X-Smtp2go-Schedule-Id header, which you can use with webhooks to monitor delivery.

Additionally, we've added two new endpoints:

• /email/scheduled/search - Retrieve a list of up to 1,000 scheduled emails matching the supplied parameters.
• /email/scheduled/remove - Remove an email scheduled for sending by schedule_id).

We've launched a new feature that makes verifying your sending domain easier than ever! Our new automated verification process, powered by Entri, is a trusted solution for seamless DNS changes.

You now have two simple options to add the CNAME records to your domain's DNS: manually or automatically. For a streamlined experience, simply choose the automatic option. You'll be prompted to log in securely to your DNS via Entri, and the necessary records will be added automatically - no more manual entry required.

For a full breakdown of this new process, check out our Verified Senders article.

We've recently released a new feature which makes it possible for a master account to share the ability to send from a sender domain to its subaccounts. This change will make it much easier for situations where multiple subaccounts are needing to use the same domains within a master account, as only one set of DNS records will need to be created.

To get started, see the new 'Subaccount access' tab when adding or editing a sender domain.
