AgentiSend vs Brevo
Yes, AgentiSend is a Brevo alternative for outbound mail an agent sends under a per-key budget, while Brevo hosts data in France and Germany. The send path refuses with agent_budget_exceeded when that budget is spent, and a key cannot raise its own. A Free plan that does not expire: 3,000 emails a month, 100 a day, 3 domains, no card. Then plans from $9 a month (Starter, 30,000 emails). No plan daily cap; delivery paced per inbox provider. Or 40% off paid yearly.
Pick Brevo when you want data hosted in France or Germany, unlimited transactional log retention, a dedicated IP on Enterprise, or SMS and WhatsApp on the same account; pick AgentiSend when an agent holds the key and you want a per-key budget and a kill switch. The figures below are from Brevo pages fetched on 21 October 2026 and from this product's pricing table and published API.
| What matters | AgentiSend | Brevo |
|---|---|---|
| Trying it before paying | A Free plan that does not expire: 3,000 emails a month, 100 a day, 3 domains, no card. Then plans from $9 a month (Starter, 30,000 emails). No plan daily cap; delivery paced per inbox provider. Or 40% off paid yearly. | The transactional page calls the free plan forever free, with no card: 300 emails a day, which it also writes as 9,000 a month. Starter starts at $9 a month for 5,000 emails. |
| Price at 5,000 emails a month | $9 a month on Starter, which covers 30,000 emails, so $0.30 per 1,000 at the inclusion. | Starter starts at $9 a month for 5,000 emails. Standard starts at $18 a month for 5,000. Professional starts at $499 a month for 150,000. Enterprise is custom. |
| A spending limit per key | Every key is created with a send budget. The send path refuses with agent_budget_exceeded when it is spent, and a key cannot raise its own. The plan inclusion is a second ceiling (plan_limit_reached). | A per-key send budget is not on the pricing page or the transactional page. |
| A retry never sends twice | Idempotency-Key is accepted on every endpoint that changes something and remembered for 7 days. | The transactional page says idempotency is a UUID kept for 30 minutes so a retry does not send twice. The idempotency page says a key reused within 30 minutes returns a duplicate_parameter error and the request is not processed. It does not say the first result is returned. |
| What a refusal tells you | Every refused request carries code, message, fix (the call that repairs it), docs_url and retryable. | The idempotency page names duplicate_parameter when a key is reused within 30 minutes. A field named fix that names the next call is not on that page. The inbound events reference lists a code and a message on a failure, and does not name a fix field. |
| How long the log keeps a message | 7 days on Free, 30 on Starter, 90 on Pro, 180 on Scale. It is part of the plan and there is no add-on to buy. | The pricing page says every plan includes transactional email with unlimited log retention. The transactional page calls retention flexible, including on the free plan, and does not restate a day count. The inbound events reference returns the last 30 days when no range is set, and a chosen range cannot exceed 30 days. |
| What the model can call | A hosted MCP server with 92 MCP tools (46 listed by default, the rest named by list_more_tools). An agent gets the same budget and kill switch over MCP as over the API. | A hosted server at https://mcp.brevo.com/v1/brevo/mcp covers 27 modules, including contacts, campaigns, transactional templates and dedicated IPs. A token is sent as a bearer credential. The page does not give a tool count. |
| Audited security reports | None yet. No SOC 2 report and no penetration-test letter exist, and /security says so. | The transactional page says ISO 27001 certified, and GDPR, CCPA and CASL compliant. It also says regular security audits. A SOC 2 report is not named on that page or the pricing page. |
| Where the data sits, and a dedicated address | Not offered. Customer data is processed in the United States. Dedicated IP on request. Once one is assigned, the published ramp is 20% of volume to day 7, 40% to day 14, 60% to day 21, 80% to day 28, then all of it, on GET /dedicated-ips/ramp. | The transactional page says data hosting is in France and Germany. Enterprise lists a dedicated IP. The same page says dedicated IPs are available for high-volume senders, with automated warming. A price for the address is not on those pages. |
| Receiving mail | Receiving is a switch on each verified domain: publish one MX record and mail to that domain is stored on your account, with extracted_text beside the raw body, a clear or review label on every message, an optional hold until a person releases it, and allow and block rules per domain. There is no inbox object; the domain is the address. | The transactional page lists inbound parsing. The inbound events reference lists received-mail events. With no date range it returns the last 30 days, and a chosen range cannot exceed 30 days. |
| SMS and WhatsApp | The published API sends email. It has no SMS or WhatsApp operation. | The transactional page says the same account sends transactional email, SMS and WhatsApp. |
