Sendblue vs Sendinblue (Brevo)

These Are Completely Different Products

Let's get this out of the way: Sendblue and Sendinblue (Brevo) are entirely different companies that happen to have similar names. The confusion is understandable — Sendblue gets over 181,000 search impressions from people looking for "Sendinblue" — but the products couldn't be more different.

Sendblue is an iMessage and RCS API for developers and businesses. It lets you send and receive iMessages programmatically, build conversational workflows, and integrate Apple's messaging ecosystem into your product. Think: texting your customers from your app via iMessage.

Sendinblue (which rebranded to Brevo in May 2023) is an email marketing and CRM platform. It lets you send email newsletters, manage email campaigns, build landing pages, and run SMS marketing. Think: Mailchimp or HubSpot.

If You're Looking for Email Marketing

If you came here searching for Sendinblue to send email campaigns, manage subscriber lists, or set up marketing automation — you want Brevo (formerly Sendinblue). They're great at what they do, and we're happy to point you in the right direction.

Sendblue doesn't do email. That's not our product, and we won't pretend otherwise. Brevo offers:

• Email campaigns and newsletters
• Marketing automation workflows
• Built-in CRM and contact management
• Transactional email via API
• Landing page builder
• SMS marketing campaigns

If You're Looking for iMessage API

If you need to send iMessages from your application, integrate iMessage into your CRM, or build automated iMessage workflows — you're in the right place. Sendblue is the leading iMessage API, and it's the only product in this comparison that supports iMessage at all.

With Sendblue, you get:

• iMessage API — send and receive iMessages programmatically
• RCS and SMS fallback — automatic fallback for non-Apple devices
• Group messaging — multi-party iMessage conversations via API
• Rich media — send images, videos, contact cards (vCards), and links with previews
• FaceTime Audio — programmatic FaceTime calls that bypass spam filters
• HIPAA compliance — SOC 2 certified with BAA support for healthcare
• MCP server & CLI — developer tools for AI agents and terminal workflows

Brevo cannot send iMessages. No email marketing platform can — iMessage requires specialized Apple infrastructure that only dedicated iMessage API providers like Sendblue operate.

If You Need Both Channels

Here's the good news: Sendblue and Brevo are complementary, not competitive. Many businesses use both products together as part of a multi-channel communication strategy.

A common setup looks like this:

• Brevo handles email newsletters, drip campaigns, and bulk email communications
• Sendblue handles high-priority 1:1 conversations via iMessage — sales follow-ups, appointment reminders, customer support, and time-sensitive notifications

Email and iMessage serve different purposes. Email is great for broadcasting to large lists at low cost. iMessage delivers 98% open rates and is ideal for conversations that need to actually be read and responded to. Using both gives you the best of both worlds.

Why the Name Confusion?

Sendblue and Sendinblue have similar names purely by coincidence. Sendinblue was founded in France in 2012 as an email marketing tool. Sendblue was founded in the United States as an iMessage API platform. The names overlap enough that search engines frequently mix them up.

In May 2023, Sendinblue rebranded to Brevo — partly to differentiate their brand. However, many people still search for "Sendinblue" out of habit, and searchers looking for "sendinblue login" or "sendinblue pricing" often land on Sendblue's website instead.

If you're one of those people: no worries. You can find Brevo at brevo.com. And if you're curious about what Sendblue actually does — our iMessage API might be exactly what you didn't know you needed.
