Which one, for whom

Pick Intercom if

  • Your support lives in the website messenger and in-app, and you want product tours and outbound messages in the same tool.
  • Fin's AI quality matters more to you than its per-outcome price.
  • You need email in the price, which Brevo (Sendinblue) does not include outright.
  • You need a ticket queue, which Brevo (Sendinblue) does not have.

Pick Brevo (Sendinblue) if

  • You already send campaigns from Brevo and want the same contacts in the inbox.
  • Marketing automation matters as much as support.
  • Five people cost $350 a month less than on Intercom ($75 against $425), before AI.
  • You need WhatsApp and Instagram in the price, which Intercom does not include outright.

The third option: Sellio

  • Your team is two to ten people on chat, messaging and email. Weigh workspace pricing against $425 a month on Intercom against $75 on Brevo (Sendinblue) for five people; the billing units and included features differ.
  • You want a ceiling on AI spend: Intercom meters AI (from $0.99 per outcome) above the seats, Brevo (Sendinblue) meters AI (Aura AI) above the seats, and Sellio stops at the cap you set.
  • You need Telegram and native Windows and macOS apps, which neither Intercom nor Brevo (Sendinblue) includes.

What two, five and ten people pay

Intercom on Advanced: $170, $425 and $850 a month for two, five and ten people, before AI. Brevo (Sendinblue): $75 a month for five (5 seats × about $15); it does not print a per-seat rate to extend to two or ten. Sellio: Free for two seats; Mini at $45 for five, $380 less than Intercom and $30 less than Brevo (Sendinblue) for five people; Essentials at $95 for ten, the AI credit included. At ten people, Essentials at $95 is $755 under Intercom.

Where the two agree, and where they split

Intercom is a customer messaging platform built around the Messenger; Brevo (Sendinblue) is a marketing platform with a chat inbox built around email campaigns. Only Brevo (Sendinblue) has a free plan (one seat, one channel); Intercom offers a 14-day trial, no card. Intercom and Brevo (Sendinblue) both include website chat in the price; only Intercom has email; only Brevo (Sendinblue) has WhatsApp and Instagram. Neither Intercom nor Brevo (Sendinblue) includes Telegram outright. Intercom (from $0.99 per outcome) and Brevo (Sendinblue) (Aura AI) both meter AI above the seats. Intercom has tickets and Brevo (Sendinblue) does not, and neither Intercom nor Brevo (Sendinblue) ships a desktop app. Intercom is an afternoon for a website-first team; Brevo (Sendinblue) is an afternoon.

What each price leaves out

Intercom: Fin AI agent from $0.99 per outcome on every plan; Copilot $29 per agent per month yearly ($35 monthly). WhatsApp, SMS and phone are pay-as-you-go. Brevo (Sendinblue): Aura AI drafts and summaries inside the plans; no per-conversation AI price. Beside Intercom's from $0.99 per outcome and Brevo (Sendinblue)'s Aura AI, Sellio includes an AI credit with each paid plan. Usage consumes that credit; additional credits cost extra, and you can set a spending cap.

How these figures were read

Brevo (Sendinblue) does not print the figures above in a form a fetch can read (Conversations is priced per seat; the marketing plans by email volume. The page could only be read in a local currency, so the seat price is from Brevo's published summaries.), so they are marked unverified here beside Intercom's, and Brevo (Sendinblue)'s pricing page should be checked before you decide.
