The MailChannels Zapier integration lets you send email through the MailChannels Email API whenever an event fires in another app — a form submission, a new CRM contact, a placed order, or any of the thousands of triggers Zapier supports. You build the workflow once in Zapier’s visual editor, and MailChannels handles delivery every time the trigger fires.
The MailChannels app on Zapier is currently in Beta. It works reliably, but you may see the Beta label when searching for it in the Zapier app directory.

​
What you need before you start

  • A MailChannels account — sign up at mailchannels.com.
  • A Zapier account — free or paid, available at zapier.com.
  • A domain you own — MailChannels sends email on behalf of your domain and requires a one-time DNS setup described below.

​
Setting up the integration

1

Create a MailChannels API key

Zapier uses your API key to authenticate with MailChannels on your behalf.
  1. Log in to the MailChannels Console.
  2. Go to Account Settings.
  3. Under API Keys, click Create API Key.
  4. Give it a description (e.g., Zapier) and set the Scope to api.
  5. Copy the key and store it somewhere safe — you will not be able to view it again.
While you are in the console, note your Account ID shown in the upper-right corner. You may need it during domain setup.

Authorize your sending domain

MailChannels uses Domain Lockdown to verify that you own the domain your emails will come from. You configure this once in your domain’s DNS settings.Add a TXT record at your domain registrar with the following values:
FieldValue
Host_mailchannels.<your-domain>
Valuev=mc1; auid=<YOUR_ACCOUNT_ID>
DNS changes typically take a few minutes to a few hours to propagate.
Your domain must also have a valid SPF record that includes MailChannels, and at least one A or MX record. Without these, MailChannels may not deliver mail for that domain.
Set up DKIM for your domain in the MailChannels Console under Settings → DKIM. DKIM signing significantly improves deliverability and reduces the chance your emails land in spam.

Connect MailChannels to Zapier

  1. In Zapier, click + Create → Zaps.
  2. Give your Zap a name, such as Send Welcome Email via MailChannels.
  3. Navigate to the Action step and search for MailChannels.
  4. Select MailChannels from the results.
  5. For Action Event, select Send Email.
  6. In the Account section, click Sign in.
  7. Enter your MailChannels API key when prompted, then confirm.
MailChannels is now connected to your Zapier account. This connection is reusable — you only need to authenticate once.

Configure your email fields

After authenticating, click Continue to reach the email configuration screen. Fill in the following fields:
FieldDescription
From (Email Address)The address you are sending from — must use the domain you authorized in step 2, e.g. hello@acme.com
From (Display Name)(Optional) The name recipients see, e.g. Acme Support
To (Email Address)The recipient’s email — click the field to insert a dynamic value from your trigger
To (Display Name)(Optional) The recipient’s name, also available as a dynamic field
SubjectYour subject line — supports dynamic values
Body (HTML)The email body — supports HTML and dynamic values for personalization
In any field, click inside it to browse and insert data from your trigger step — such as the submitter’s name, email address, or order number. This is what makes each email feel personally addressed without extra work.
Example HTML body:
<p>Hi {{first_name}},</p>
<p>Thanks for signing up! We're excited to have you on board.</p>
<p>– The Acme Team</p>
Once all fields are filled in, click Continue, then Test Step. Zapier sends a real test email using your sample trigger data. Check the inbox to confirm it arrived.

Set up your trigger

The trigger is the event in another app that starts the automation. Go to the Trigger step at the top of your Zap and configure it.
  1. Search for your app and select it.
  2. Choose the event that should start the email, e.g. New Submission.
  3. Connect your account and follow the prompts.
  4. Click Test Trigger to pull in sample data — this data will be available to personalize your email.
Common trigger apps and events:
  • Form submissions — Typeform, Google Forms, Gravity Forms
  • New contacts — HubSpot, Salesforce, Pipedrive
  • New orders — Shopify, WooCommerce
  • Spreadsheet rows — Google Sheets, Airtable
  • Scheduled time — Schedule by Zapier (great for recurring emails)
6

Publish your Zap

Once the test is successful:
  1. Click Publish to turn the Zap on.
  2. Your automation is now live — every time the trigger fires, MailChannels sends the email automatically.

​

Troubleshooting

I can’t find MailChannels in Zapier’s app search. The integration is currently in Beta. Search for MailChannels directly, or use the direct link: zapier.com/apps/mailchannels/integrations. My test email wasn’t delivered.
  • Make sure the From address uses the same domain you authorized in step 2.
  • Confirm your Domain Lockdown TXT record has propagated.
  • Verify your domain has a valid SPF record and at least one A or MX record.
Email went to spam.
  • Set up DKIM in the MailChannels Console under Settings → DKIM.
  • Confirm your SPF record is valid.
  • Consider adding a DMARC record. See the MailChannels DMARC guide.
Zapier shows an authentication error. Your API key may have been deleted or rotated. Generate a new one in the MailChannels Console, then reconnect in Zapier under My Apps → MailChannels → Reconnect.
