| Which plan to pick | Try Free first. Most small businesses should go straight to Standard, because it removes Brevo's logo and adds automations. Pick your email volume carefully, since that's what you pay for. Yearly billing saves 10%, and prices vary by country. | Start on Free and build your welcome and abandoned cart flows before you pay anything. Move to Email when you cross 250 contacts, and only add SMS once email is working, because text messages cost extra per send. | Most small businesses should take the hosted Team plan for the team access and AI images. Standard works for a solo creator. Self-host only if you or someone on your team is comfortable running a server. |
