Add your new OptinMonster subscribers to SendinBlue

Good to know: We no longer provide support for this plugin.


OptinMonster integrates directly with SendinBlue and can help you: 

  • generate more subscribers by using advanced subscription forms, including the option to improve your forms through A/B testing,
  • automatically add all of your new OptinMonster subscribers to your preferred SendinBlue contact list. 

In this guide, you'll learn how to connect OptinMonster with SendinBlue and sync contacts collected by your OptinMonster forms to Sendinblue. 

Before getting started

You will need to gather the following information:

  • Your SendinBlue account credentials. If you don't have one, sign up for free.
  • Your SendinBlue API v2 key following the instructions here. You'll have the option to create a new v2 API key and give it a descriptive name, such as “OptinMonsterAPIKey” for use specifically with this integration.
  • Your OptinMonster account credentials. If needed, you can create an OptinMonster account here. Plans range from $9 to $49 per month and they offer a 14-day money-back guarantee if you are not satisfied after testing the tool. 

Integrating OptinMonster with SendinBlue

Go to the Campaigns Builder, and click the Integrations button on the left panel. 



Click the “New integration” button and select SendinBlue from the Email Provider dropdown. 




Next, paste your newly created API key into the provided field. Make sure you also add a label to the SendinBlue account you’re connecting, so you can re-use the connection at a later time without having to repeat these steps. OptinMonster_setup_4.png


Now that you have connected OptinMonster to SendinBlue, OptinMonster has access to your contact lists.

Select the email list you want to add subscribers to with this campaign, or go back to SendinBlue and create a new list before you get started.


And that’s it! Your OptinMonster contacts will now automatically be added to your chosen SendinBlue contact list.
