Postmark alternative
A Postmark alternative with a permanent free plan and mailboxes
Rovela is a transactional email API with a permanent free tier — something Postmark does not offer. It adds business mailboxes on your own domain, idempotency keys to prevent duplicate sends, and inbound email processing alongside clean delivery webhooks. DKIM-signed from your own domain on every message, free plan, no card required.

开发者为什么迁移过来
A free plan that does not expire
Postmark's test credits run out; then you pay from the first message. Rovela's free plan is permanent — 100 emails and 5 mailboxes every month, no card, no conversion pressure.
Mailboxes your team can actually read
Postmark is a sending service. Rovela includes browser-accessible mailboxes on your domain, so the people who get your transactional mail can reply to it from the same platform.
Idempotency keys built in
Postmark does not expose idempotency keys. Rovela prevents duplicate sends at the API layer — resubmit the same key within 24 hours and you get the original response, not a second message.
常见问题
- 迁移到 Rovela 需要多长时间？
- 大多数团队 30 分钟内即可通过 Rovela 发信。添加发信域名，更新一条 DKIM DNS 记录，在代码里替换 API 端点和密钥，就可以上线了。企业邮箱配置再多几分钟。
- 切换时需要修改 DNS 记录吗？
- 需要，但通常只有两条：DKIM TXT 和 SPF TXT。Rovela 控制台会显示具体的值；只有域名还没有 DMARC 时才会建议加一条。如果域名托管在 Cloudflare、阿里云或 DNSPod，Rovela 可以一键应用这些记录。
- 可以继续使用现有的发信域名吗？
- 可以。Rovela 支持使用您拥有的任意域名发信。添加一条 DKIM TXT 记录和一条 SPF TXT 记录进行验证后，所有邮件都将以该域名签名发出。您也可以逐步迁移，先让部分流量走 Rovela，剩余的保留在原来的服务商。
- 免费套餐和付费套餐有什么区别？
- 免费套餐每月包含 100 封邮件和 5 个企业邮箱，无需绑卡，永不过期。付费套餐提升邮件数量和邮箱数量上限。所有套餐（包括免费）均包含 DKIM 签名、投递 Webhook、幂等键、邮件接收和完整的投递日志。
