FAQ
Is Brevo good for SaaS?
Brevo handles basic email sending well and is affordable, but it lacks SaaS-specific features: no custom product event tracking, no trial conversion sequences, no dunning support, and no native billing integration. For SaaS lifecycle email, Loops or Sequenzy are better choices.
Is Brevo cheaper than Loops?
Brevo starts at $25/mo for 20K emails with unlimited contacts, making it cheaper for raw email volume. But it lacks SaaS features. Sequenzy at $19/mo includes billing integration and lifecycle workflows.
Does Brevo support transactional email?
Yes. Brevo has a mature transactional email service with both API and SMTP relay options. This was its original product (as Sendinblue). SMTP relay makes integration very easy.
Which has better deliverability?
Brevo large sender base can lead to inconsistent shared IP reputation. Sequenzy SaaS-only pools and Loops smaller base tend to have more consistent deliverability. A dedicated IP ($20/mo on Brevo) helps significantly.
Can Brevo connect to Stripe?
Brevo has a basic Stripe integration, but it is designed for e-commerce payment events, not SaaS subscription lifecycle. Sequenzy has native Stripe integration for SaaS billing events.
Does Brevo have a CRM?
Yes. Brevo includes a CRM with deals, pipeline, and task management. Neither Loops nor Sequenzy has a built-in CRM.
Can I use Brevo for SMS marketing?
Yes. Brevo supports SMS, WhatsApp, and chat natively. Neither Loops nor Sequenzy supports SMS.
Should I migrate from Brevo to Loops?
If you are a SaaS company, migrating to Loops or Sequenzy will give you SaaS-specific features (event tracking, lifecycle automation, billing integration) that Brevo lacks. Migration is straightforward for contacts and templates.
What is the difference between Brevo and Sendinblue?
Brevo is the rebranded name for Sendinblue (renamed in 2023). Same company, same product, new name reflecting expanded capabilities beyond email.
Which is better for a non-technical team?
Brevo is accessible for non-technical teams with its visual editor and SMTP relay for easy transactional setup. Loops is also intuitive with a cleaner UI. Sequenzy pre-built templates reduce the need for technical setup.
