Short answer: Brevo (formerly Sendinblue) pairs a transactional email API and SMTP relay with a marketing suite — contact lists, campaigns, and SMS marketing — on one account. Devotel Orbit is the AI-first omnichannel platform: the same transactional-email envelope — the send API plus an SMTP relay, with SPF, DKIM, and DMARC domain authentication — running on the same account as AI voice agents, SMS and MMS, WhatsApp, RCS, embeddable video, and a built-in contact center, on one pay-as-you-go bill.
Pick Brevo when the scope really is email plus list marketing alone, with a marketing-owned campaign canvas as the centrepiece. Pick Orbit when a transactional email has to share one unified customer profile and one bill with the rest of your channels. The row-by-row matrix lives at /compare/brevo.
1. What Brevo actually is
Brevo's public surface covers two halves, and the honest read credits both:
- Transactional email over an API and an SMTP relay. Brevo exposes a REST send API plus an SMTP relay with API-key-based authentication, so a legacy SMTP-wired system joins the same pipeline as the API path.
- A marketing suite on top. Contact lists, drag-and-drop campaigns, and SMS marketing run as first-class products on the same Brevo account. That is a genuinely broader scope than a pure transactional-email vendor — and it is a scope Orbit deliberately does not claim.
Orbit's email pillar is transactional-scope: the send API, an SMTP relay, templates, attachments, engagement tracking, and suppression. A team-owned list-marketing product is not a parity row the /compare/brevo matrix claims, and one is not fabricated.
2. The shared envelope: where the two platforms tie
The rows a transactional-buyer shortlist actually weighs resolve at parity:
- Send API. Both platforms expose a transactional send endpoint on an API key; the payload shape carries over.
- SMTP relay. Brevo's relay and Orbit's SMTP relay are genuine parity both ways: Orbit's relay is a shipped ingress endpoint (smtp.orbit.devotel.io, ports 587, 465, and 2525, TLS required) authenticated with the same tenant API key that gates the HTTP endpoint — one credential covers both paths. The full connection profile is documented at Send email through the SMTP relay.
- Domain authentication (SPF, DKIM, DMARC). Both require a verified sending domain; the verification dance is the same, so the migration is a DNS re-point, not a rebuild.
- Deliverability health. Both ship deliverability tooling. Orbit adds DMARC aggregate-report ingest plus automatic spam-complaint and bounce suppression on top of the domain-authentication grid — a row the /compare/brevo matrix credits as an Orbit lead rather than a tie.
3. Where Brevo remains the right choice
- A marketing-owned campaign canvas is the product. If the program's centrepiece is drag-and-drop list marketing — newsletters, promo sends, list segmentation — with transactional email riding alongside, Brevo's suite shape is a feature set Orbit does not replace.
- An email-plus-SMS-marketing-only program. If contact lists plus transactional sending genuinely are the entire scope — no voice, no contact center — the all-in-one bill advantage dissolves and a dedicated marketing platform is a defensible shape.
Pick Orbit instead when the email program shares a customer profile with everything around it: a receipt email should fall back to SMS when the mailbox bounces, a suppression decision should hold across email and SMS, and the contact center should read the same send history.
4. Migration sketch: one send call, DNS first
A Brevo-to-Orbit move mirrors the move from every dedicated email vendor, in the order that keeps delivery green:
- Reuse your sending domain. The authenticated domain you already run on Brevo transfers as-is; register the same sender domain in Orbit's dashboard (Settings → Email) and re-publish the SPF, DKIM, and DMARC records Orbit specifies so the DNS proof flips cleanly.
- Repoint the send call or the relay endpoint. For API integrations, swap the API key and endpoint your app posts to — the payload shape carries over. For SMTP clients, change the relay host to
smtp.orbit.devotel.io(port 587 STARTTLS, or 465/2525) and authenticate with the same tenant API key that gates the HTTP endpoint, so both ingress paths cut in one move. - Export every suppression category out of the old account before the first send and re-import it so bounce, complaint, and unsubscribe state holds across the cutover.
- Move inbound replies onto Orbit's inbound parse webhook so replies land in the shared inbox, then shut off the old account once delivery is green.
5. Frequently asked questions
Can I reuse my sender domain when I migrate from Brevo?
Yes. Domain verification attaches the DNS proof to the same domain — register the sending domain in Orbit, republish the SPF, DKIM, and DMARC records Orbit specifies, and the recipient side of your sending traffic does not change shape. The migration is a DNS re-point, not a domain rebuild.
Does Orbit replace Brevo's marketing list and campaign suite?
No. Orbit's email pillar is deliberately transactional-scope, and this post credits Brevo's broader suite rather than claiming parity on it. What Orbit does add is the rest of the stack on the same account: AI voice agents, SMS and MMS, WhatsApp, RCS, embeddable video, and a built-in contact center — one account, one bill.
What is Orbit's pricing model compared to Brevo's?
Brevo prices email and its marketing suite as subscription tiers scoped to email and list marketing. Orbit is pay-as-you-go with published per-email pricing and bundled credit across every channel, so transactional email draws from the same account balance as SMS, voice, and the rest of the stack — the rate you see is the whole cost: no per-product fees, no carrier or compliance surcharges, and no paid support tier stacked on usage. Compare the current published terms on both vendors' pricing pages before committing.
What if I only move my SMTP-based sending first?
The SMTP relay cutover is the bounded version of the move: update the relay host and credential, let the same tenant API key authenticate submissions, and the suppression and consent gates apply identically to relay and HTTP ingress. The relay connection profile (host, ports, credential shape) is at Send email through the SMTP relay.
