Transactional emails are emails sent directly through the API. They are typically used for one-to-one communication, such as password resets, order confirmations, and notifications. The /v1/send endpoint supports up to 50 recipients per request.

​
Automatic contact creation

Every transactional email sent via /v1/send automatically creates or updates a contact for each recipient.
  • If the recipient already exists, their contact is updated with any new metadata you provide.
  • If the recipient is new, a contact is created automatically.
  • If your active contact limit is reached, MailGlyph creates the recipient as a pending contact so the email can still be delivered.

​
Sending with attachments

MailGlyph supports sending attachments with transactional emails. You can include up to 10 attachments per email, with a maximum total size of 10MB. Attachments should be base64 encoded and included in the attachments array when sending the email via the /v1/send endpoint.

​
Sending from a template

You can also send transactional emails using a template you have created in the dashboard. This allows you to reuse the same design and content for multiple emails, while still personalizing them with contact data.
