SendGrid and Mailgun are both email APIs: your code calls them, and they deliver each email to the inbox. SendGrid has been part of Twilio since 2019 and sells Marketing Campaigns as a second product. Mailgun, built for developers sending from code, is part of Sinch, which sells marketing email separately as Mailjet.

Need a complete notification engine around SendGrid or Mailgun? Choose SuprSend
SuprSend is an agentic notification platform that sits above your email provider. It decides whether a message goes, on which channel, when and to whom, and retries through the other provider if the first does not confirm delivery. Tenants, workflows, translations and preferences are built in, and the same trigger also reaches push, SMS, WhatsApp, Slack and an in-app inbox. SendGrid and Mailgun deliver the email you hand them; the logic stays in your code.

MailgunMailgun is better for developers who want a free plan that does not expire, 30 days of logs on Scale, a choice of US or EU region on every plan, and an MCP server agents can send through.
Which is cheaper, SendGrid or Mailgun?
Both bill by emails sent a month. Up to about 12,750 emails Mailgun is cheaper: Basic is $15 for 10,000, then $1.80 per 1,000. From there to 50,000 SendGrid is cheaper, because Essentials covers 50,000 for $19.95 and Mailgun Foundation is $35. With a dedicated IP included, SendGrid Pro at $89.95 and Mailgun Scale at $90 differ by five cents for 100,000 emails.
How do I move from SendGrid to Mailgun?
Verify your sending domain in Mailgun, swap the SendGrid SDK or SMTP credentials for Mailgun’s, rebuild dynamic templates as Mailgun templates, point webhooks at Mailgun’s events, and carry over your suppression lists. SendGrid subusers become Mailgun subaccounts, which need an Enterprise plan. Mailgun publishes a SendGrid migration guide.
Can I use SendGrid and Mailgun together?
Yes. Verify the same domain with both and choose the vendor per message in your code, for example one for transactional email and the other for bulk sends. Each keeps its own suppressions, templates and webhooks, so your code has to keep them in step.
Can SuprSend send through SendGrid or Mailgun?
Yes. SuprSend, which publishes this page, connects to both and can fall back from one to the other.
