Give your agents full access to Resend.
Agents compose and send transactional and lifecycle email from your own domain. Pair Resend with a database or CRM and an agent writes the message with the context each recipient deserves.
Capabilities
What agents do with Resend
Helios vector-searches the Resend API surface at run time, so an agent reaches for whichever endpoint the task needs.
- Search Resend's entire API surface at run time and call any endpoint your key allows.
- Send individual and batch emails from your verified domain.
- Compose HTML and plain-text bodies tailored per recipient.
- Manage audiences and contacts for lifecycle sequences.
- Read delivery events to confirm what landed and what bounced.
- Combine with database queries so each message reflects real account state.
Use cases
Tasks you can hand to a Resend agent
Run an onboarding sequence that reads the account
Instead of a fixed drip, the agent checks what each new account has actually done and sends the message that helps next.
Daily, email new accounts based on what they have set up so far.
- postgres·list accounts created in the last 14 days
- code·determine each account's next milestone
- resend·send 46 tailored emails
46 onboarding emails sent
- 19 nudged to connect their first integration
- 14 shown how to schedule a task

Notify people when something needs them
Any agent that finds a problem can also tell the right person about it, with the detail they need to act.
When a nightly task finds a data issue, email the on-call analyst.
- postgres·run data quality checks
- code·summarize the 2 failing checks
- resend·email the on-call analyst
Data quality alert sent
- `orders.currency` null on 41 rows since 02:10
- Upstream job `ingest_orders` last succeeded at 01:55
Send a weekly customer digest
Each customer gets a summary of their own numbers, written from their data rather than a template with slots.
Every Monday, send each account a digest of last week's usage.
- clickhouse·aggregate weekly usage per account
- code·write per-account narrative
- resend·batch send 312 digests
312 digests sent
- Each names the account's top workflow by runs

Follow up on failed payments
When billing finds a problem, the agent writes a clear message with a working link and sends it from your domain.
For each failed charge, email the billing contact with an update link.
- stripe·list failed charges
- stripe·create hosted payment update links
- resend·send recovery emails
3 recovery emails sent
- Sent from [email protected]
- Each links a hosted update page
- Escalation scheduled if unpaid in 48h
Cross-app recipes
Resend works alongside the rest of your stack
One agent, one run, several services. It reads from one tool and writes to the next without a handoff.
Templates
Ready-to-run Resend agents
Copy the prompt, connect your tools, and put an agent on the task.
Sales & RevOps
Failed payment recovery
Finds failed charges every hour, emails the billing contact a working update link, and escalates the accounts that matter.
Sales & RevOps
Typeform lead router
Reads each form response, enriches the company, routes it to sales or support, and replies while the person still has your tab open.
Sales & RevOps
Onboarding email that reads the account
Checks what each new account has actually set up and sends the message that helps them next, rather than the next message in a sequence.
Operations
Nightly data quality checks
Runs your invariants against production every night and tells the on-call analyst which rows broke and since when.
Use cases
Where Resend agents earn their keep
Database reporting
An agent introspects your schema, writes the SQL, runs it, analyzes the results in its own sandbox, and posts a report your team reads — instead of a dashboard nobody opens.
Billing operations
An agent watches Stripe for failed charges and starts recovery, reconciles what you billed against what your own system recorded, and reports the revenue numbers every morning.
Email outreach
An agent finds the threads that went quiet, reads the conversation, and drafts a follow-up grounded in the last real next step. Onboarding sequences read the account before they send.
Form routing
A response arrives and an agent reads what the person wrote, enriches their company, decides where it belongs, and files it — as a deal, a support thread, or a reply within minutes.
