Automate Resend

Keep an eye on the email your product sends through Resend. Bounces and spam complaints get flagged as they happen, failed sends are rounded up in a daily digest, and the addresses causing trouble reach the people who can fix them. Describe what you want to your AI assistant, check what it will do, and it keeps running with your laptop closed.

Try asking

Create a ClickRuntime automation: when Resend reports a bounce or spam complaint, email me at ops@mycompany.com with the recipient, subject and reason.

Paste it into your assistant. It tells you what it will send or change before it runs live.

Ideas

Know straight away when a message bounces or lands as spam, and get one tidy list of delivery problems at the end of the day. These are ready-made starting points. Anything else you can describe works too.

Build your own

Build any Resend automation you can describe

The ideas above are ready-made starting points, not a fixed list. Describe what Resend should do in your own words, with your conditions, other apps or an AI step, and your assistant writes it, tests it and runs it on ClickRuntime.

  • Your own rules

    Conditions, thresholds, filters and exceptions, written the way you'd explain them to a colleague.

  • Any number of apps

    One automation can read from one app and update several others. Over 248 apps are ready, and anything with an API works too.

  • AI where it helps

    Summaries, classification, extraction and drafts use ClickRuntime's built-in AI, with no extra key.

  • On a schedule or on each event

    Runs as often as every 5 minutes, or the moment an app sends an event, and keeps track of what it already handled.

For example, ask your assistant

Every week, have AI write a short product update from my notes and send it through Resend to my customer list, skipping anyone who unsubscribed.

When a new user signs up in Supabase, send a welcome email through Resend with their first name.

When a Stripe payment fails, send the customer a Resend email with a link to update their card, log it in a Google Sheet and post it in Slack.

Beyond chat

Have Resend work when you're not in the chat

Connecting Resend to ChatGPT or Claude lets you ask about it while you chat. ClickRuntime handles the part that should happen on its own: checks on a schedule and actions on each new event, set up from the same chat and running after you close it.

Setup

Connect Resend

You connect Resend with an API key you create in your own Resend account. You pick whether it has full access or can only send, and for which domain.

Resend

Email (transactional)

  1. In Resend, open API Keys and choose Create API Key.
  2. Pick a permission: Full access, or Sending access limited to one domain. Watching bounces through a webhook needs a full access key, or you can add the webhook yourself in Resend.
  3. Copy the key, which starts with re_. Resend only shows it once.
  4. In the ClickRuntime dashboard, open Connections & secrets and save the key as a secret for Resend.

Good to know

Resend limits that affect automations

  • Resend applies its rate limit per team, not per key. Your Settings → Usage page shows the value for your account, and automations wait and retry when Resend asks them to slow down.
  • Sending to any recipient needs a verified domain in Resend. Without one, you can only send to your own address.
  • Resend's webhooks can deliver the same event more than once, so bounce and complaint alerts skip events they have already handled.
  • A sending-only key can send email but can't set up webhooks or read other data.

FAQ

Questions about automating Resend

What can ClickRuntime do in my Resend account?
Whatever your key allows. A sending-only key can send email from its domain. A full access key can also create the webhook that reports bounces, complaints and other delivery events.
How fast do bounce alerts arrive?
As soon as Resend reports the event. Resend posts it to the automation's own link, the signature is checked, and the alert goes out straight away.
Will I get the same bounce twice?
No. Resend can send an event more than once, so the automation remembers each email ID and ignores repeats.
Can it send email through Resend for other automations?
Yes, with a key that has sending access and a verified domain. That lets alerts and reports from other apps go out from your own domain.
Do I need AI for Resend automations?
No. Delivery alerts and digests run without it. If you want a summary or a drafted message, that uses the AI that comes with every ClickRuntime plan, so you don't need your own AI key.
Is this a Resend connector for ChatGPT or Claude?
Not for chatting with Resend data. A chat connector lets your assistant read and change Resend while you're in the conversation. ClickRuntime is for the work that should happen without you: you set up an automation from the chat once, and it keeps running on a schedule or on each Resend event.
