Brevo

Brevo is an all-in-one customer relationship suite covering email marketing, SMS, WhatsApp campaigns, chat, and a built-in CRM. It was founded in 2012 by Armand Thiberge as Sendinblue and rebranded to Brevo in 2023. The company is headquartered in Paris, France, and is one of the largest European players in the category.

The free plan allows 300 emails per day with unlimited contacts, which is unusual — most competitors cap contacts instead. Paid plans start at around $9 per month and are priced by email volume rather than list size, which suits businesses with large but infrequently mailed lists.

The affiliate program uses a hybrid payout that rewards both halves of the funnel: €5 for each free signup and €100 for each paid subscription. Getting paid on free registrations is rare and makes the program far easier to earn from than pure revenue-share alternatives.

Tracking runs on PartnerStack with a 90-day cookie. Rewards are calculated at the end of each month and cashed out via PayPal or Stripe, with a minimum payout threshold of roughly €100.
