Connect SMTP.com to LettrLabs
When New Sending Event fires in SMTP.com, your agent runs Send Purchase Event in LettrLabs. Describe the whole flow and it is built, tested on every scenario and kept running.

Build solutions, not workarounds.
What do you want SMTP.com and LettrLabs to do together?
Ask the assistant
Connect your AI client
Give your AI client this address.
https://mcp.apiant.aiOne connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

Questions
SMTP.com and LettrLabs, 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 LettrLabs when something happens in SMTP.com?
Any of LettrLabs's 5 actions, including Send Purchase Event, Add Address Book Entry, Get Conversion and List Conversions. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from LettrLabs to SMTP.com?
LettrLabs has no triggers in the catalog today, so automations start in SMTP.com. If you need the other direction, ask: your agent reads LettrLabs's API documentation and adds it.
Do I have to build a connector for SMTP.com or LettrLabs?
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 LettrLabs 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.
