Mailgun 替代方案

Mailgun 替代方案

Mailgun 是 Sinch 旗下产品，与 Mailjet 一起归属于 Sinch Email 业务线；SendGrid 是 Twilio 旗下产品，目前正在整合到 twilio.com。因此，Mailgun 最明显的两个替代选项与你可能正在离开的 SMS 供应商属于同一个 CPaaS 母公司。在迁移之前，这一点值得了解。

The rest of the choice is concrete. Mailgun's API accepts multipart/form-data and puts your sending domain in the URL path; newer platforms take JSON payloads. Bird is on this list alongside the cases where another provider is the better answer.

团队为什么会寻找 Mailgun 的替代方案？

Two reasons recur, and neither is about deliverability. The first is the request format: Mailgun's send endpoint uses multipart/form-data with the sending domain in the URL path, a 2010 convention that newer platforms have replaced with JSON. The second is ownership. Mailgun has been part of Sinch since the Pathwire acquisition and is sold alongside Mailjet, so a team consolidating vendors sometimes finds it is still managing separate products under one parent.

Bird

适合希望将邮件与其他通信渠道整合在一起、并且希望智能体能够操作邮件的团队。 Bird's send endpoint accepts JSON with built-in idempotency headers and replay detection, so a retry after a timeout does not send twice. Thirteen email webhook event types cover the lifecycle from accepted through bounced, complained, and unsubscribed, and the same workspace and key run SMS, WhatsApp, voice, Verify, and Realtime. The hosted MCP server at mcp.bird.com lets an agent send and inspect a domain after a browser sign-in. The tradeoff is scope: if you want a standalone email API with no other channels, a single-channel provider is a smaller surface to own.

Resend

Best for a small product team that wants a fast first send. Resend positions itself as the email API for developers and offers fast onboarding with React Email for templates written as components. If your team is building an application from scratch, this is an easy place to start. It is also the youngest platform here, so the operational surface is thinner than Mailgun's on long event retention and inbound routing.

Postmark

P

Best for transactional email where speed to the inbox is the primary requirement. Postmark separates promotional from transactional traffic with Message Streams so bulk sends and receipts stay isolated on distinct delivery paths. The deliberate limit is the other side of that discipline: it is a focused transactional product, so a team that also wants multi-channel campaigns, SMS, or WhatsApp will need a second vendor.

Amazon SES

适合已有周边基础设施的高发送量场景。 SES is the lowest-cost way to put high volumes of mail on the wire and bills strictly on usage, which is why it remains the default for teams already inside AWS. What you take on is the application layer above the send: SES gives you the delivery pipe, while templates, suppression workflows, event storage, and reporting are yours to build and operate.

Twilio SendGrid

适合安全审查已经通过的知名品牌。 SendGrid is the most widely deployed email API in the category, which in an enterprise procurement cycle saves weeks of review. Keep the parent structure in mind: as Twilio SendGrid, its web presence is folding into twilio.com, so it carries the same parent-portfolio question that Mailgun does under Sinch.

MailerSend

适合非工程师负责模板的混合团队。 MailerSend 自称是团队友好型邮件 API，确实如此：模板编辑和相关权限专为营销人员和开发者在同一账户中协作而设计，并提供八种语言以及 SMS 和 WhatsApp 的示例。如果你的瓶颈是工程师需要手动部署每次文案修改，这个产品可以消除它。

Brevo

Best when the real requirement is marketing campaigns and a built-in CRM. Brevo describes itself as an email and SMS marketing, CRM, and automation platform, and that ordering is honest: the transactional API exists, while the core product centers on campaigns, contacts, and automations. If your team has been using Mailgun to send marketing mail and building the audience tooling internally, Brevo replaces both.

大家实际会问的问题

Mailgun 和 Sinch 是同一家公司吗？
Mailgun 是 Sinch 旗下产品。Sinch 收购了 Mailgun 的母公司 Pathwire，现在将 Mailgun 与 Mailjet 一起归入其 Email 业务线销售。这在实际中有一层含义：如果你正在从 Sinch 迁出 SMS 或语音服务，将邮件迁到 Mailgun 意味着你仍然在同一个供应商旗下；同理，如果你正在离开 Twilio，迁到 SendGrid 也是一样。
我的代码实际上需要改什么？
Mailgun's send is a multipart/form-data POST to api.mailgun.net with your sending domain in the URL path, authenticated with HTTP Basic using the username api. Bird's send is a JSON POST with a bearer key and the domain passed as a field in the payload. The migration guide maps the fields and webhook events so the update is straightforward.
哪个替代方案最便宜？
For raw volume with no features attached, Amazon SES is the lowest-cost option. Factor in what your team builds on top: suppression handling, templating, event storage, and reporting come built into the other platforms on this page and are yours to maintain on SES. Compare each provider's published rates against your own monthly volume.
AI 代理能操作我的邮件账户吗？
On Bird, yes: point an MCP client at mcp.bird.com, sign in through the browser, and an agent can send, look up a message, and inspect a sending domain against the workspace without a static API key in a config file. Check the other providers directly if agent access is part of your requirements.
Bird 是本页的正确选择吗？
If you want email on the same platform and key as SMS, WhatsApp, voice, and Verify, and you want agents able to operate it, yes. If email is the single channel your team sends and you want a dedicated single-channel tool, Postmark or Resend is a strong fit. If you want the lowest raw cost per message and will build the surrounding tooling, SES wins. If the job centers on marketing campaigns and a CRM, Brevo fits.
