Bavimail

Bavimail describes itself as "One email API for humans, apps, AI agents". It is email infrastructure for developers: one REST API and dashboard for transactional sends such as password resets and order confirmations, marketing sends such as newsletters and announcements, inbound email processing, and inboxes for AI agents. The home page says all of it can also be driven from Claude, Cursor or Cline through Bavimail's MCP server, and that the service starts free with no credit card. Its FAQ sums the product up as "A complete email infrastructure platform" that lets customers send mail, manage domains and identities, track deliverability and process inbound mail through a single API.

The home page counts 13 webhook events, 2 official SDKs, 10K+ emails handled and 20K+ events processed, and the transactional email feature page was last updated in April 2026.

Sending through the API

Sending starts with an official SDK for TypeScript or Python, and the plain HTTP API works from any language that can make standard HTTPS requests. The home page headline promises "Sending in under five minutes": install the SDK, verify a domain, and ship a first send. In code, a send names an alias ID for the sending identity, the recipient address, a subject and an HTML body, and the transactional page shows per-message flags to turn open and click tracking on. Aliases can be listed through the API to discover the identities an account can send from. The transactional feature page describes the aim as a single surface for sending app email, managing domain health and reacting to delivery outcomes, keeping DNS, authentication and MAIL FROM guidance next to the sending workflow instead of splitting them across tools.

For larger workloads, outbound processing covers batch sends for campaigns and scheduled, timezone-aware delivery, so a message can be set to arrive at, for example, 9am in each recipient's local time. Domain setup runs through the API as well: a domain is created with inbound switched on or off, and the SDK returns its DNS setup and verification status. The domain verification guide walks teams through SPF, DKIM, DMARC and MAIL FROM, and the agent section of the home page says those records are configured automatically.

Tracking, webhooks and reputation

Open tracking is described as pixel-precise, and click analytics capture and report every link click so a sender can see which content drives action. Event webhooks send real-time HTTP callbacks for delivered, opened, clicked, bounced and complained events. The webhooks are signed: the sample code verifies each payload with a signature header, a timestamp header and a webhook secret before acting on an event such as email.outbound.delivered, for example to reconcile the state of a message in the app's own records, and the webhook docs cover the event model, signature verification and retry patterns.

Reputation management includes automatic domain health checks, suppression lists, bounce handling and deliverability monitoring, and the dashboard preview shows a domain health score, SPF, DKIM and DMARC pass status, suppression sync, bounce rate and a blocklist scan. The analytics API returns a deliverability summary for a chosen range and a list of recent deliverability events. On IPs, the FAQ says a dedicated IP is not needed to get started, since "Our shared IP pools are carefully managed for high deliverability," and that dedicated IPs are available for larger commercial arrangements when a customer needs full reputation control.

Inbound email and AI agent inboxes

Inbound processing covers MX record management, email parsing and intelligent routing to webhooks or mailboxes. Incoming mail arrives as a signed webhook with the parsed body, attachments and threading, so an application handles a reply the same way it handles any other event. The site also says inbound is included on every paid plan.

The agent features build on that. Bavimail pitches a real inbox for every AI agent a team ships, for fleets that handle support tickets and customer replies over two-way email. One API call gives each agent its own sending alias on the customer's domain, such as support@, billing@ or agent-42@, with no shared mailbox and no OAuth. Bounces, complaints and suppression sync run in the background. Because the API is plain REST, the page says it works with LangChain, CrewAI, n8n or anything else that can make an HTTP request, and the MCP server lets coding assistants and agents operate the account directly.

Plans and pricing

The pricing section offers monthly and annual billing across four plans:

• Free: 200 daily outbound emails and 524,288,000 bytes of attachment storage, with no credit card required.
• Developer: $5 a month, unlimited daily outbound email and 5,368,709,120 bytes of attachment storage.
• Startup: $50 a month, 300,000 total monthly emails and 32,212,254,720 bytes of storage.
• Scale: $500 a month, 2,500,000 total monthly emails and 1,000 GB of storage.

The site also says email validation is bundled rather than sold separately. For anything beyond the listed plans there is a "Talk to sales" link.

Migration and support

For teams moving from another provider, the FAQ says the REST API follows standard conventions so most integrations translate directly, that "Most teams complete migration in under a day," and that Bavimail provides guides for common providers. Documentation includes a platform overview with a launch sequence and production checklist, an API reference for sending, inbound, domains, analytics and suppressions, webhook docs and SDK guides with working examples. Support questions go to support@bavimail.com, and the footer links a status page, GitHub and Twitter.

Who it suits

Bavimail suits developers and small product teams who want one API for everything their app sends and receives: password resets, newsletters, customer replies and agent inboxes on the same SDK, dashboard and bill. The free plan covers prototyping, and the $5 Developer plan lifts the daily cap for a small production app. Teams building AI agents that need to send and answer email on their own domain get a purpose-built model with per-agent aliases, signed inbound webhooks and MCP access.

The site calls itself email infrastructure for developers and AI agents, so a marketing team that works without engineers is not its audience, and teams planning volumes beyond the Scale plan or wanting a dedicated IP will be arranging terms with sales.
