In order to provide a reduced latency for this resource we have modified the default limit to be 50 results per page and 100 as a maximum. If you have specified a different limit than the recommended one, then we suggest you to do the necessary changes.

It is now possible to schedule transactional messages to be sent in the future. You can define a single transactional email or configure a batch send-out with millions of versions.

You can now create contact import jobs using a complete JSON definition for your contact attributes.

You can now use your unique HTML code and edit it when sending transactional messages in batches.
Just edit the variable htmlContent for each message version you want to create.

We have (again) increased the rate limit for the batch sending functionality of our Email API.
You can now call the endpoint up to 100x per minute, this meaning you can send out a maximum of 6.000.000 emails per hour.

• We now allow users to pass a set of contacts with their updated fields in one single API call via a JSON payload.
• Each contact can have different fields overwriten/updated through this call.
• In a single call each contact can be identified with a mix of id or email or sms

We have increased the rate limit for the batch sending functionality of our Email API.
You can now call the endpoint up to 5x per minute, this meaning you can send out a maximum of 30 000 emails per hour.

Passing the IdempotencyKey in the transactional email headers now allows you to be sure the request will be processed only once and that not repeated emails will be sent to your recipients mailbox.

It's now posible to define special characters as non-unicode. Whenever the flag is set to false any unicode characters in the message payload will be converted to their english equivalents.
