How to Connect Sendinblue

First of all, you should make sure you have created an account and subscribe to Sendinblue's free plan and you have completed your profile details plus their requirements, you can register by clicking here if you have not done that already.

Then, log in to the account and follow these 3 steps to complete the SMTP connection:

  1. Authorize your domain

  2. Verify your DNS records

  3. Create, copy and integrate Sendinblue's API

Authorize your domain

From your Sendinblue Dashboard, click on "Settings" menu. At "Your Sender and Domains" boxed click on Configure button, move to Domains tab and click "Add a New Domain", enter your domain URL, check the box below then click "Save".

Note: If the page doesn’t respond (as at now that page is buggy this way), do not worry because it is saved anyway, you could just click on the transparent area to leave that pop-up and now the “saved successfully” confirmation dialogue should come up and your domain should now start showing there and if not, then refresh that page and it would come up.

Verify your DNS records

After adding the domain, click the "Authenticate This Domain" button which will reveal DNS text records, add these record to your hosting by contacting hosting supports for guidance and don't worry, it is quite an easy process.

Note that some hosting could take up to 24 hours for new records to take effect, but when it's done, go back to Sendinblue and click "Authenticate This Domain" button again to verify the records one by one by clicking "Record Added. Please Verify it" and finally click "I'm done" after verifying all.

Create, copy and integrate Sendingblue's API

This is the last process which is quite easy because we will connect Sendinblue by using the available Sendinblue API and a direct link to this API page is available next to the API's field or just click here to visit the page. You could either create a new key there in 2 clicks or just copy the existing key you see.


The Sendinblue mailer will not be able to work on your site until you’ve completed these three processes involved in the settings.
