Migrate from Mailjet

47 seconds from key paste to first production send. Zero downtime, and a 30-day path back if you change your mind.

BEFORE YOU START✓ Your Mailjet API key✓ Access to your DNS records✓ Five minutes

STEP 01

Paste your Mailjet API key

wemail reads your Mailjet account and auto-imports templates, suppression lists and bounces. Nothing is changed on the Mailjet side. A test API key is yours immediately.

STEP 02

Change one line

The shim speaks Mailjet's wire format — keep your client, change the host.

SEND.TS · NODE

import Mailjet from "node-mailjet";

const mj = Mailjet.apiConnect({

key: process.env.MJ_KEY,

// everything else unchanged

+ url: "https://api.wemail.io"

});

await mj.post("send").request({ … });

STEP 03

Verify your domain & test send

Add the DNS records wemail generates, then fire a test send. Searchable logs and signed webhooks are live from your very first event — production unlocks once the sender is verified.

STEP 04

Cut over gradually

Weighted DNS shifts traffic 0% → 100% over 60 minutes while Mailjet and wemail run side by side. Watch both streams in the live activity feed. Downtime: 0ms.

STEP 05 — OPTIONAL

Roll back anytime

Mailjet stays warm for 30 days. If anything feels off, one API call moves DNS back in under a second — no support ticket, no waiting.
