Integration
Connect SMTP.com and Watermelon
When New Sending Event fires in SMTP.com, your agent runs Add Contact in Watermelon, or New Contact in Watermelon to Send Email in SMTP.com. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.

Questions
SMTP.com and Watermelon, answered
What can start an automation from SMTP.com?
Any of SMTP.com's 1 trigger in the catalog, including New Sending Event. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Watermelon when something happens in SMTP.com?
Any of Watermelon's 8 actions, including Add Contact, Find Contact, Find Conversation and Get conversation. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Watermelon to SMTP.com?
Yes. When something happens in Watermelon, your agent can act in SMTP.com too. This page covers both directions: Watermelon's triggers and SMTP.com's actions are listed here as well.
Do I have to build a connector for SMTP.com or Watermelon?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use SMTP.com and Watermelon without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
