Questions
MailerSend and Poplar, answered
Can a MailerSend unsubscribe stop someone getting printed mail from Poplar?
Yes. The unsubscribe trigger in MailerSend can add that email address, and the postal address or user ID if you hold one, to your Poplar Do Not Mail suppression list, and the agent tests each scenario before it goes live.
Poplar has no triggers, so can anything start in Poplar?
No, Poplar only offers actions here, so every run starts from a MailerSend event such as a delivery, click, bounce or spam report. Poplar then does the work, like adding an audience member, reporting an order or updating a suppression list.
What can start an automation from MailerSend?
Any of MailerSend's 11 triggers in the catalog, including Email Is Clicked Through, Email Is Delivered, Email Is Hard Bounced and Email Is Reported as Spam. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Poplar when something happens in MailerSend?
Any of Poplar's 7 actions, including Add Audience Member, Add Email to Do Not Mail List, Add Order and Add User ID to Do Not Mail List. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Poplar to MailerSend?
Poplar has no triggers in the catalog today, so automations start in MailerSend. If you need the other direction, ask: your agent reads Poplar's API documentation and adds it.
Do I have to build a connector for MailerSend or Poplar?
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.
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.
