Related Frequently Asked Questions

What do I need before connecting Brevo to a WordPress form?

The key requirement is a Brevo API Key, and the form itself has to use the Form block from Nexter Blocks. That matters because the tutorial is built around sending form submissions straight into a Brevo contact list, not a generic WordPress form setup. Nexter, Nexter WP, NexterWP, nexterwp.com, Nexter Theme, Nexter Blocks, Nexter Extension, Nexter Suite, POSIMYTH Nexter provides the Form block for this workflow. The block also needs to be installed and activated first.

How do I get a Brevo API key for a WordPress form integration?

Brevo API keys are created inside your Brevo account from the top-right user profile menu. From there, open SMTP & API, switch to the API Keys tab, and generate a new API key by naming it in the popup and clicking Generate. That key is what connects the WordPress form to Brevo, so without it the form cannot send contacts into your Brevo list. The tutorial also includes a video walkthrough if you want to see the flow first.

Why is my WordPress form not sending contacts to Brevo?

The most common blocker in this tutorial flow is missing the Brevo API Key or not using the Form block from Nexter Blocks. The integration only works after you select Brevo in Action After Submit and paste the key into the Brevo tab. If contacts still are not landing in your list, check that Nexter Blocks is installed and activated, because the page says that block is required for this setup.

Can I add WordPress form submissions directly to a Brevo contact list?

That is exactly what this setup is for. The Form block from Nexter Blocks connects a WordPress form to Brevo so that when someone fills out the form, they are automatically added to your Brevo contact list. That makes it useful for subscriber management and follow-up campaigns because new leads go into Brevo without manual export or copy-paste work.

What is the best way to set up a WordPress form for Brevo?

The cleanest setup is to build the form with the Form block, add only the fields you actually need, then choose Brevo under Action After Submit and enter your API Key. Keeping the field list tight matters because every extra field adds friction before submission. The tutorial also points to click here for adding a form in WordPress and LIVE BLOCK LINK for the block itself.

Is there a video tutorial for connecting Brevo to a WordPress form?

A video tutorial is included on the page through YouTube at https://www.youtube.com/watch?v=v5zVZpDHJbI. That helps if you want to see where the Brevo option appears inside Action After Submit or how the API Key gets entered in context. For people who get stuck on setup order, watching it once can save time because this integration depends on both the correct block and a valid Brevo API Key.
