Connect Mailjet to RadarSend

Mailjet is an email sending service. Once you connect it, RadarSend hands your emails to Mailjet to deliver, and Mailjet reports back what happened to each one.

Before you begin#

  • A Mailjet account (sign up at https://www.mailjet.com).
  • An authenticated sender or domain in Mailjet.
  • Access to your domain’s DNS settings (to add SPF and DKIM records).
  • A RadarSend account with admin access.

Step 1 — Get your Mailjet credentials#

  1. Sign in to Mailjet.
  2. Authenticate your domain / sender. Open Senders & Domains, add your domain, and follow Mailjet’s prompts to verify it by adding the SPF and DKIM DNS records to your domain. (In the current app this area is sometimes labeled Account Settings → Domains and Senders; look for the option to add and validate a domain.)
  3. Get your API keys. Go to Account Settings → REST API → API Key Management and copy both the API Key (the public key) and the Secret Key (the private key). You’ll need both in the next step.

Step 2 — Add the sending service in RadarSend#

  1. In RadarSend, go to Settings → Sending → Sending services and click + Connect a service.
  2. In the wizard, on Choose your sending service, pick Mailjet and click Continue.
  3. On Enter your Mailjet keys, fill in your API Key and Secret Key, then click Create.

RadarSend validates the fields and saves the service — it doesn’t live-test Mailjet, so you’ll confirm sending actually works in Step 4.

Step 3 — Turn on delivery, bounce & complaint tracking#

Set this up manually so RadarSend knows what Mailjet did with each email.

  1. Open the service (Settings → Sending → Sending services → your service). The Webhook delivery section shows a webhook URL unique to your account (it looks like https://…/webhooks/mailjet/…). Copy it.
  2. In Mailjet, go to Account Settings → Event Notifications (also called triggers) and set the endpoint URL to the URL you copied.
  3. Enable the Sent, Bounce, and Spam events.
  4. Back in RadarSend, click Check to confirm the triggers are on.

Step 4 — Confirm your sending address#

  1. Go to Settings → Sending → Senders and click + Add sender.
  2. Enter your Sending address (on your authenticated Mailjet domain), click Continue, add a Display name and Reply-to, pick your email types, and click Continue.
  3. On Tracking & confirm, choose this service under Sending service (only if you have more than one), enter a test recipient, and click Send test.
  4. When the test is accepted, click Save sender.

If the test is rejected because your domain isn’t authenticated, RadarSend offers Authenticate {domain} (DKIM/SPF) and shows the exact DNS records to add.

Tip: Open the service and click Check verified domains to see which senders and domains Mailjet has authenticated.

Common issues#

  • Only entered the API Key. Mailjet needs both keys — the public API Key and the private Secret Key. Sending fails if either is missing or mistyped.
  • Sender or domain not authenticated. Mailjet won’t send from a domain that hasn’t passed SPF/DKIM verification. Finish authentication in Senders & Domains and re-run the test.
  • Wrong events enabled. RadarSend relies on the Sent, Bounce, and Spam events. If tracking looks empty, confirm those specific events are turned on (not, say, only Open or Click).
  • Multiple free accounts. Mailjet doesn’t allow one customer to run several free accounts. If sign-up or sending is blocked, consolidate into a single account.
  • Looking in the wrong menu. The keys live under Account Settings → REST API → API Key Management, not under your profile or a billing page. Don’t confuse the Secret Key with your login password.

Good to know#

  • Mailjet uses two keys — a public API Key and a private Secret Key — and RadarSend needs both together as your credentials.
