Easy authentication with tokens

Customizable token permissions

For extra security, set permissions to limit the areas of your account that API tokens can access. Grant full access to endpoints for all parts of your accounts or use custom access to choose specific areas.


Safeguard your sending domain

Protect your sender reputation using our SPF, DKIM and DMARC security protocols. Authenticate your email content to improve your email deliverability and keep out of the spam folder.
