Both send email over a REST API. Every row below was read from Rasket's own pages and Brevo's own pages, and the day they were read is printed under the table.
Rasket is an email API for developers: one REST API and a dashboard for transactional email and campaigns, with inbound mail, signed webhooks and an MCP server in the same product and on the same key.
Brevo is a marketing platform with a transactional email API attached: an SMTP relay, seven official SDKs, authenticated webhooks, inbound parsing, idempotency keys for batch sends and an MCP server.

Facts checked on against each company’s public pricing and documentation.
Brevo reaches further than email. Campaigns, contacts, a CRM and conversations live in the same account, so a small team that would otherwise buy three products can buy one. Their free plan sends 300 emails a day where ours allows 100 emails a day, their pricing FAQ promises unlimited log retention where we keep 30 days, and they publish seven official SDKs while ours are still coming. Their send endpoint also has a published ceiling of 1,000 requests a second on every plan, and up to 2,000 on Professional and 6,000 on Enterprise.
Brevo is best for: Teams who want marketing, CRM and transactional email from one vendor
Brevo's price list favours Rasket at volume: 50,000 emails a month is $56 on Brevo Starter against $20 a month for 50,000 emails on Rasket. The product rows split. Brevo's webhooks are protected by an IP allowlist, a password or a token rather than a signature over the payload, and its idempotency keys cover batch sends for 30 minutes, where Rasket signs every event, replays it on request and remembers any send's key for 24 hours. Choose Brevo if you want marketing, CRM and email from one vendor or a bigger free plan; choose Rasket if email is the whole job.

It is, if what you want is an email API rather than a marketing suite. Rasket signs and replays webhook events, versions templates, and costs $20 a month for 50,000 emails where Brevo Starter is $56 at 50,000 emails. Brevo covers ground Rasket does not — a CRM, conversations, SMS — and its free plan and log retention are both larger than ours.
Brevo: Yes. Inbound parse webhooks, documented in their developer guide. Rasket receives mail at your own domain on every plan, including the free one, and delivers each message to a signed webhook with its headers, text, HTML and attachments.
Rasket. Brevo's Starter plan is $9 for 5,000 emails and its price list adds a $47 step for 40,001 to 50,000, so 50,000 emails is $56; Rasket is $20 a month for 50,000 emails. Brevo sells volume in steps rather than per thousand, so check the step that covers your own month on their price list.
Yes. Point any app that sends over SMTP at smtp.rasket.com on port 465 or 587, with the username rasket and an API key as the password, and each message becomes an ordinary API send: the same verified domains, suppressions, quota and webhooks. Moving an SMTP integration is a change of host and credentials, not of code.
Add the domain in Rasket and publish the generated DKIM, SPF and DMARC records; nothing about that stops Brevo sending in the meantime. Then move transactional sends to POST /emails, or point an SMTP mailer at smtp.rasket.com with the username rasket and a Rasket key, and rebuild the templates you use as Rasket templates with typed variables, published as a version. Inbound parse webhooks become a Rasket receiving domain and one signed webhook; contacts come across as a CSV import. If you are using Brevo's campaign tooling, plan that part separately — a Rasket campaign covers sending to a segment, not a CRM.
Both, genuinely. Brevo publishes an MCP server, Markdown at every developer documentation URL and an llms.txt index; Rasket publishes an MCP server with seven toolsets, a setup skill, Markdown twins, llms.txt and llms-full.txt. The distinction is scope again: Brevo's surface spans a marketing platform, so an agent has more to get right, where Rasket's is email and stops there.
Create a key, verify a domain, and send your first email the same morning. The free plan does not expire.
