Brevo (formerly Sendinblue) sits behind a lot of WordPress signup forms via its plugin or HTML embed. The form handles list selection, double opt-in, GDPR fields, and posts to the Brevo API. The signup converts when people land on the page. The page itself, however, is a regular WordPress post or page, and its social-share preview is whatever your theme defaults to. Lead-magnet pages, newsletter signups, and event-registration pages all share with a generic site logo.

SleekPixel handles the metadata layer Brevo does not try to touch. You build one template in the WordPress admin with dynamic fields like {post_title}, {offer_name}, {list_name}, and any custom field on the post. Every save regenerates the OG image. Embed a Brevo signup form in the page body, set a meta field for the offer name or list, and the share card ships with the URL.

SleekPixel does not modify Brevo itself, it works at the post level. Brevo keeps doing what it does: list management, sending, automations, transactional, and the form embed. SleekPixel handles the metadata around the form so the lead-magnet page looks intentional wherever the URL gets shared.

Lead-magnet pages are bottom-of-funnel surfaces. Each share, retweet, partner mention, or paid placement points back to a URL where the form lives, and the thumbnail attached to that URL is the moment the offer either looks specific or looks generic. A site-logo preview on every lead-magnet page tells the reader nothing about what's behind the form.

A per-page card that pulls the offer name and list directly from the post keeps the promise visible from the share onward, which directly affects opt-in rate. Brevo handles the form, the API, and the list. SleekPixel handles the metadata around the form so the page that captures the lead looks like part of the brand.
