Brevo

Brevo (formerly Sendinblue) has established itself as one of the most compelling marketing platforms for European agencies, combining email marketing, SMS, WhatsApp, live chat, and CRM in a single GDPR-compliant package. For agencies managing client communications across multiple channels, Brevo eliminates the need to stitch together separate tools for each channel while keeping all data within EU boundaries.

The platform's pricing model is one of its biggest advantages for agencies. While competitors like Mailchimp charge based on contact count, Brevo prices by email volume, which means you can maintain large contact databases without costs spiraling. The built-in CRM with deal pipeline tracking adds sales functionality that most email marketing platforms lack, allowing smaller agencies to manage their entire client acquisition process without a separate CRM. Marketing automation workflows tie everything together, triggering emails, SMS messages, or deal stage changes based on contact behavior.

Compared to Mailchimp, Brevo offers more channels and better European data compliance at a lower price point, but Mailchimp's email editor and template marketplace are more polished. Compared to ActiveCampaign, Brevo provides SMS and WhatsApp natively, while ActiveCampaign offers deeper automation logic. For agencies that need multichannel outreach with strong GDPR compliance and don't want to pay enterprise prices, Brevo hits a sweet spot that's hard to match.
