Integrating Mailjet with OptiMonk lets you gather leads with OptiMonk and use Mailjet's email marketing tools to reach them. Everyone who fills out your popup form is added to the Mailjet list you pick — no exports, no copy-paste.
Before you start: you need a campaign whose popup is already built (the field mapping is read from the input fields of your popup) and a Mailjet account.
Good to know: Mailjet is a legacy integration. You cannot start a new Mailjet connection from the campaign's Integrations tab — the provider list does not offer it. You connect the account once in the classic OptiMonk admin, and from then on it behaves like every other integration here: you attach it to a campaign, pick a list and map the fields in the Integrations tab.
1. Get your API key and Secret key in Mailjet
Log in to your Mailjet account in a new browser window and click your icon in the top right corner. Select the Account settings menu.
Select Master API Key & Sub API key management.
The page shows the API key and the Secret key. Copy both.
OptiMonk's own hint for these two fields says it in one line: You can find your API key and Secret key within Mailjet, under My Account -> Master API Key option.
2. Connect Mailjet in the classic OptiMonk admin
In OptiMonk, open the account menu and choose Go to classic admin. You are signed in there with the same account, no second login.
In the classic admin, open the campaign you want to connect and go to its integration settings, then add a new Mailjet integration.
Paste the API key and the Secret key into their fields, give the connection a name you will recognise later, and save it.
Once the connection exists on your account, you can use it in the new OptiMonk app on any campaign — you only have to do this step once per Mailjet account.
3. Attach it to your campaign in OptiMonk
Open Campaigns in the left menu and click the campaign you want to connect with Mailjet.
Open the Integrations tab of the campaign.
Click Add integration. If this is the campaign's first one, the same step is offered as Connect your email or SMS tool.
Provider step: your Mailjet connection is listed at the top under Your connected accounts, with the name you gave it (or simply Mailjet). Click it. If the list is long, type into the Search providers… box.
List step: pick the Mailjet list new signups should join, then click Continue. Use Search lists… if you have many.
Field mapping step: decide where each popup field goes in Mailjet (see below), then click Save integration.
That's it. Whenever a visitor signs up through your popup, they are added to the Mailjet list you picked. Their data also stays in OptiMonk — you find it under Leads in the left menu.
Draft vs. live: if the campaign has not been published yet, the integration is shown with a Draft pill and the note Saved as draft — it goes live when you publish the campaign. On a published campaign it shows as Active and is applied right away.
Field mapping
The mapping table has two columns: Popup field on the left (every input your popup collects) and Mailjet field on the right. OptiMonk pre-fills the mapping with its own suggestions, so in most cases you only need to check it.
The email row is fixed — it always maps to the Mailjet email field.
Pick Don't sync for any popup field you don't want to send.
Under Static fields you can send a fixed value with every submission, for example the source of the subscriber. Click Add static field, type the value on the left and choose the Mailjet field on the right.
Change or remove the integration
The Integrations tab lists every integration on the campaign with its list name.
Change list reopens the wizard at the list step, and from there you can walk on to the mapping.
Remove takes the integration off this campaign: Remove from this campaign? The account connection stays and can be added again. Your Mailjet credentials are not deleted, so you can reuse them on another campaign.
