Integration
Connect MailUp and REsimpli
When New Email Message in List fires in MailUp, your agent runs Add Contact Details to Lead in REsimpli, or New Agent in REsimpli to Create New Email Message in MailUp. 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
MailUp and REsimpli, answered
What can start an automation from MailUp?
Any of MailUp's 4 triggers in the catalog, including New Email Message in List, New Group, New Recipient Subscribed and New Recipient Unsubscribed. Describe the moment in plain language and your agent picks the right one.
What can your agent do in REsimpli when something happens in MailUp?
Any of REsimpli's 33 actions, including Create Buyer, Create Lead, Create Tag and Create Vendor. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from REsimpli to MailUp?
Yes. When something happens in REsimpli, your agent can act in MailUp too. This page covers both directions: REsimpli's triggers and MailUp's actions are listed here as well.
Do I have to build a connector for MailUp or REsimpli?
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 MailUp and REsimpli 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.
