Integration
Connect MailerSend to PostalCodes
When something happens in MailerSend, your agent does the next thing in PostalCodes. Describe it in plain language and the automation is built, tested on every branch and kept running.
Build it
What do you want MailerSend and PostalCodes to do together?
Describe it and your agent reads both APIs, builds the automation, tests every branch and ships it. The list below is what exists today, not the limit.
Ask the assistant
You'll sign in before anything runs. What you typed comes with you.
Or work from Claude Code
Install the APIANT plugin for Claude Code and build, edit, test and read run history from your terminal. Every plan gets this, including free, and it spends no assistant credits.
