Resend Zapier integrationAutomate Resend with Zapier.
The Resend Zapier integration gives you 7 actions, 0 triggers and 0 searches. Resend never starts a Zap on its own: another tool fires it, then Resend sends the email, creates the contact or files that contact into the right segment.

What the Resend Zapier integration actually does
It lets a Zap, the automation you build on Zapier, push work into Resend without a line of code. Something happens in another app, and Resend sends an email, creates a contact or moves that contact between segments. Resend only ever receives orders here: it has no event that can start a Zap.
Three results come back again and again. A welcome email that leaves on its own: a signup lands in your form tool, and Send Email fires from your verified domain. A contact list that fills itself: Create Contact files the new address, then Add Contact to Segment puts it with the people who share its plan or its language. Segments that follow the customer: when a deal closes in your CRM, Remove Contact From Segment takes the person out of the trial list.
Now the part the app page skips. Zapier cannot listen to Resend: nothing that happens on the Resend side will ever start a Zap from here. Every Zap on this page therefore begins in another tool. There is no search step either, so finding a contact goes through Retrieve Contact, which is an action and costs a task each time it works.
Hesitating between platforms? The same app has a Resend Make integration page, and our Zapier review covers what Zapier is good at outside this one app.
Zapier vocabulary in one minute
Seven words come back on every line of this page. Here they are, in plain English.
- Trigger
- The event in an app that starts the Zap. Once the Zap is on, Zapier waits for it. Resend has none, so it comes from another tool.
- Action
- What the Zap does once it has started: the step that writes, sends or moves something for you, like sending an email through Resend.
- Task
- The unit Zapier bills: one action your Zap completes successfully. The number on your plan counts nothing else.
- Polling vs instant
- A polling trigger is checked on a timer by Zapier. An instant one is reported by the app the second it happens, with no wait.
- Filter
- A step that lets the Zap continue only when what arrived meets your condition, and stops it quietly otherwise.
- Search step
- A step that looks up something that already exists in an app so the next steps can use it. Resend offers none on Zapier.
- Connection
- Your Resend account linked to Zapier once, then reused by every step that talks to Resend in any of your Zaps.
What a Resend Zap really costs
Zapier bills in tasks, and only for actions that work.
- Free plan100 tasks / month
- Steps on the free plan1 trigger + 1 action
- Premium appNo
- Trigger0 task
The trigger never costs a task, however often Zapier checks the source app. Each Resend action that succeeds counts once, so a Zap that creates a contact, files it and sends an email uses three tasks per signup. An action that fails is not counted. Resend is not a premium app, so it works on the free plan: 100 tasks a month, unlimited Zaps, a check every 15 minutes, but only two steps. Add a second action or a filter and the Zap becomes multi-step, which needs a paid plan.
Connect your Resend account
- 01
Open the Apps page
In Zapier, go to Apps and click + Add connection. You need an existing Resend account, plus write access to whatever the Zap will touch if the team that owns it is not yours.
- 02
Pick Resend
Type Resend in the dialog, select it, then click Add connection. A new tab opens on the Resend side so you can sign in to the account the Zap will use.
- 03
Grant access
Allow Zapier to act on that account. The connection then shows up in the list and every Resend step of every Zap can reuse it, so you only do this once.
Your first Zap: welcome a new signup
GoalEach new form submission becomes a Resend contact and gets a welcome email from your own domain.
- 01
Create the Zap
Click to create a Zap, then pick your form tool and its new submission event as the trigger. Test it: Zapier brings back the three most recent entries so you map on a real one.
- 02
Create the contact
Add a Resend step and choose
Create Contact. Map the email field of the form into Email, the only required box. Leave the subscription status untouched unless your form asks for consent. - 03
Send the email
Add a second Resend step,
Send Email. Fill From with an address on your verified domain, To with the form email, then write a Subject and the body of the message. - 04
Test each step
Run each step once and read what came back. Send the test email to an inbox you control: if it arrives, the From address and the domain are good to go.
- 05
Publish
Click to publish and the Zap switches on. Remember the bill: two Resend actions per signup is two tasks, and three steps means a paid plan.
The 7 Resend actions on Zapier
Resend gives you 7 actions. For each one: what it does for you, when to reach for it, and what to watch out for.
Add Contact to Segment
ActionIn Zapier“Add an existing contact to a segment.”
Files a contact who already exists into one of your segments. It needs the segment ID, plus either the contact ID or the email address.
Create Contact before this step in a new-signup Zap.Create Contact
ActionIn Zapier“Create a contact on a Resend audience”
Adds a person to your Resend contacts from an email address, the single field it insists on. You can also set whether that person starts out unsubscribed.
Create Segment
ActionIn Zapier“Create a Segment in your Resend team”
Opens a new segment in your Resend team, given nothing more than a name. It is the folder that later steps fill with contacts.
Remove Contact From Segment
ActionIn Zapier“Remove an existing contact from a segment.”
Takes a contact out of one segment while the contact itself stays in Resend. You give it the segment ID and the contact ID or email.
Delete Segment
ActionIn Zapier“Remove an existing Segment. (Does not delete the Contacts belonging to the Segment)”
Removes a whole segment by its ID. The contacts that were in it survive and stay available for your other segments.
Retrieve Contact
ActionIn Zapier“Retrieve a single contact using the Contact Id or Email”
Fetches one contact from Resend, by its ID or by its email, so the following steps can read what Resend holds about that person.
Send Email
ActionIn Zapier“Send an Email with Resend”
Sends one email through Resend, with a sender, one or more recipients and a subject as the three fields you cannot skip.
When a Resend Zap breaks
Zapier lists no Resend-specific error. The trouble comes from how Zaps behave in general.
Four situations explain most surprises. None of them is specific to Resend, and our Zapier troubleshooting page walks through the usual fixes.
Old signups are not picked up
A Zap only reacts to what happens after you switch it on. Contacts collected last month will not get the welcome email: moving that backlog is a separate job.The Zap keeps firing itself
If a Zap writes into the very place its trigger watches, it sets itself off again and again, and the task count of the month melts fast.A bulk import stalls
Import thousands of rows into the source tool at once and Zapier's flood protection can hold the batch back instead of sending a wave of emails.The same entry does not run twice
On a polling trigger, Zapier remembers what it has already seen. An edited form entry will not resend the email, which is usually what you want.
