Which one, for whom

Pick Zendesk if

  • Your support is ticket-first and email-heavy, with SLAs and a queue to manage.
  • You need phone support and a contact center in the same tool.
  • 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 $200 a month less than on Zendesk ($75 against $275), before AI.
  • You need WhatsApp in the price, which Zendesk does not include outright.

The third option: Sellio

  • Your team is two to ten people on chat, messaging and email. Weigh workspace pricing against $275 a month on Zendesk against $75 on Brevo (Sendinblue) for five people; the billing units and included features differ.
  • You want a ceiling on AI spend: Zendesk meters AI (per automated resolution) 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 Zendesk nor Brevo (Sendinblue) includes.

What two, five and ten people pay

Zendesk on Suite Team: $110, $275 and $550 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, $230 less than Zendesk 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 $455 under Zendesk.

Where the two agree, and where they split

Zendesk is a help desk suite built around tickets and a queue; 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); Zendesk offers a 14-day trial of Suite Professional. Zendesk and Brevo (Sendinblue) both include website chat and Instagram in the price; only Zendesk has email; only Brevo (Sendinblue) has WhatsApp. Neither Zendesk nor Brevo (Sendinblue) includes Telegram outright. Zendesk (per automated resolution) and Brevo (Sendinblue) (Aura AI) both meter AI above the seats. Zendesk has tickets and Brevo (Sendinblue) does not, and neither Zendesk nor Brevo (Sendinblue) ships a desktop app. Zendesk is a project; Brevo (Sendinblue) is an afternoon.

What each price leaves out

Zendesk: AI agents are billed per automated resolution on top of the seat price; the Copilot add-on is $50 per agent per month. Brevo (Sendinblue): Aura AI drafts and summaries inside the plans; no per-conversation AI price. Beside Zendesk's per automated resolution 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 Zendesk's, and Brevo (Sendinblue)'s pricing page should be checked before you decide.

How to decide in an afternoon

  1. Step 1

    Count agents and channels

    Anyone who replies is a seat. List the channels customers actually use.
