AI agents for MailerSend
A Monmo agent works in MailerSend the way an operations hire who looks after your app's email would. It rewrites templates in the builder, reads activity to answer support questions, reviews the suppression and blocklist entries, sorts mail arriving through inbound routes and reports on each domain. It uses an API token you scope, and asks before it sends or changes a setting.

What agents do in MailerSend
Rewrite a template in plain language
It reads a template your app uses, such as the shipping notice, rewrites the copy so it is shorter and clearer, keeps the personalisation variables, and sends you a test before saving.
AskMake the shipping notice template shorter and friendlier. Keep the variables and send me a test first.
Answer a delivery question from support
When a customer says an invoice email never came, the agent searches MailerSend's activity for that address, reads each event and drafts the reply for your support team in Zendesk or Help Scout.
AskCheck whether the invoice email to li@harbor.co was delivered on Monday and draft a reply for support.
Review suppressions and the blocklist
Each month it reads hard bounces, spam complaints, unsubscribes and blocklist entries, spots patterns such as one company domain rejecting everything, and suggests what to fix or keep blocked.
AskSummarise this month's MailerSend suppressions by type and domain, and suggest any that need a fix.
Sort mail from an inbound route
For an address your inbound route forwards to your app, it reads what arrived, separates replies, bug reports and unsubscribe requests, and drafts the next step for each. Records change only after you approve.
AskGo through replies that came in on the inbound route this week and sort them into bugs, questions and unsubscribes.
Report on each sending domain
Every Monday it reads analytics for each domain, compares delivery, opens and clicks with the week before, and writes a short summary to Slack with links to the messages behind any drop.
AskEvery Monday, send me MailerSend's weekly numbers per domain and point out anything that dropped.
Set up a new sender identity
When a team needs to send as billing@ or hello@, it prepares the sender identity and the DNS records the domain still needs, and checks the result after you approve the change.
AskWe want to send receipts from billing@ourstore.com. Prepare what MailerSend needs and tell me what to approve.
How it connects
- 1You connect MailerSend once with an API token from your own account. MailerSend lets you limit a token to certain domains and give it full or custom access, so you can keep it to the jobs you hand over.
- 2You choose which agents may use MailerSend. A support or engineering agent fits; a social media agent would never need it.
- 3Reading activity, analytics, templates and suppressions needs no approval. Sending a message, saving a template, adding a sender or route, and removing an address from a suppression list each ask first.
Questions people ask
Can an AI agent manage MailerSend templates?
Yes, with your approval on each save. A Monmo agent reads the template, edits the copy or layout you asked about, keeps every personalisation variable and sends you a test. Saving the new version waits for your approval, so your app never picks up a template you have not seen.
How do I limit what the agent can do in MailerSend?
Create a token with only the access the work needs. MailerSend tokens can be restricted to chosen domains and given custom permissions, for example read access to activity and analytics but no sending. In Monmo you also decide which agents may use the connection, and every write still asks first.
Can it handle replies that arrive through inbound routing?
It reads and sorts them, then prepares the next step: a reply draft, a ticket or an issue. Anything that sends mail or creates a record shows a card first. The agent works through the MailerSend connection, or in its own browser when the connection does not cover something.
Is MailerSend a good fit with an AI agent if we also use MailerLite?
Many teams keep newsletters in MailerLite and app email in MailerSend. One AI agent can work across both: drafting the newsletter in one, checking receipts and resets in the other, and writing one weekly report that covers all of your email in a Google Sheets tab.
