AI agents for SendGrid
A Monmo agent works in SendGrid the way an engineer on email duty would. It traces why a customer never got a password reset, reads bounce and spam report lists, edits dynamic templates, checks sender authentication and writes a weekly deliverability report. It uses an API key you create, and asks before it sends, changes a template or removes an address from a suppression list.

What agents do in SendGrid
Trace an email a customer never got
Give it the address and roughly when. The agent looks up the message in email activity, reads whether it was delivered, deferred, bounced or dropped, and tells support in Zendesk what happened and what to do next.
AskA customer at jo@example.com says the password reset never arrived yesterday. Find out what happened.
Review bounces and spam reports
Every Monday it reads the bounce, block and spam report lists, groups them by domain and reason, and flags anything unusual, such as a sudden run of bounces from one mailbox provider.
AskEvery Monday at 9, summarise last week's bounces, blocks and spam reports by domain and reason.
Edit a dynamic template
It reads the template's Handlebars variables, rewrites the copy you want changed, checks that every variable still matches what your app sends, and saves a new version only after you approve it.
AskRewrite the order confirmation template so it mentions the new returns window. Keep every variable as it is.
Check sender authentication
Before a new domain goes live it compares the DNS records SendGrid asks for with what is published in Cloudflare or your DNS host, and lists anything missing for SPF, DKIM or DMARC.
AskCheck whether mail.ourshop.com is fully authenticated in SendGrid and tell me which DNS records are missing.
Prepare a marketing single send
For a newsletter or announcement it drafts the email, picks the list or segment in Marketing Campaigns, adds the unsubscribe group, and schedules it only once you have read the card.
AskDraft a single send announcing the API changelog to the developers segment for Tuesday morning.
Clear a suppression after a fix
When a customer has fixed their mailbox and wants mail again, it finds their address on the bounce or block list and prepares the removal. Removing it always asks first.
AskSam fixed his inbox. Check if sam@northwind.io is suppressed and prepare the removal for my approval.
Report by category
It reads stats for each category your app tags, such as receipts, resets and digests, and writes delivered, open and bounce rates side by side in Google Sheets, so a drop in one stream stands out.
AskMake a sheet of last month's SendGrid stats by category, with week-by-week delivered and bounce rates.
How it connects
- 1You connect SendGrid once with an API key you create in your own account. A restricted key with only the scopes the agent needs is a sensible choice, and a subuser key keeps it to one stream of mail.
- 2You choose which agents may use SendGrid. An engineering or support agent fits; most of the team never needs it.
- 3Reading activity, stats, templates and suppression lists needs no approval. Sending mail, saving a template, scheduling a single send, changing authentication settings or removing a suppression asks first.

Questions people ask
Can an AI agent find out why a SendGrid email bounced?
Yes. A Monmo agent looks up the message in SendGrid's activity and bounce lists, reads the reason the receiving server gave, and explains it in plain words: a full mailbox, a blocked domain, a typo in the address. It then suggests the next step, such as fixing DNS or asking the customer for another address.
What API key permissions does the agent need in SendGrid?
Only the ones for the jobs you give it. For reports and troubleshooting, read access to stats, activity, templates and suppressions is enough. Add send or template write access if you want it to prepare sends and template versions, which it still asks before using. You can revoke or rotate the key at any time.
Will an AI agent send transactional email through SendGrid?
Your app keeps sending its own transactional mail. The AI agent works around it: tracing problems, editing templates and checking deliverability. If you ask it to send a one-off message or schedule a marketing send, it shows you the recipients and the content on a card first.
Can it edit SendGrid templates without breaking our code?
It is careful about that. Before saving, the agent lists every Handlebars variable in the old and new versions and checks them against the payload your app sends, which it can read in GitHub. A new version is saved only after you approve, and the previous one stays in SendGrid.
