Sendhiiv vs Mailgun

Pricing compared

Sendhiiv prices are live (USD ≈ ₦1,360/$). Mailgun column verified June 2026 against mailgun.com/pricing. Mailgun bills overages on top of plan allowances; figures marked (est.) are our calculations from Mailgun's published overage rates and will vary with usage.

Why developers switch from Mailgun

No overage surprises. Mailgun's plans include a fixed allowance, then bill $1.10–$1.80 per 1,000 extra emails automatically. A single busy month can quietly turn a $35 plan into a much larger bill. Sendhiiv's pay-as-you-go is a flat $0.20 per 1,000 with credits that never expire, and the monthly tiers don't punish you for going over.

Lower at every tier. 50,000 emails is $9/mo on Sendhiiv versus $35 on Mailgun Foundation; at half a million a month Sendhiiv is a flat $79 while Mailgun's Scale plan plus overages climbs toward several hundred dollars.

A real inbox, included. Sendhiiv gives you actual receiving mailboxes with webmail and runs on managed, monitored sending infrastructure with SPF, DKIM and DMARC setup guidance. Mailgun focuses on outbound with inbound routing, and reserves dedicated IPs for its higher tiers or as a paid add-on.

What to know before you switch

Mailgun is a mature, developer-respected platform with genuinely strong email validation, detailed analytics and reporting, an EU sending region for data-residency needs, and deep deliverability tooling. If those capabilities are core to your workflow, Mailgun earns its price. Sendhiiv's bet is different: the essentials — reliable transactional and marketing email with a clean API and SMTP — at a lower, more predictable cost, plus pay-as-you-go billing and a built-in inbox.

Migrating from Mailgun takes minutes

On SMTP, migration is just a host and credential swap — zero code changes. On the HTTP API, you move from Mailgun's form-encoded request to Sendhiiv's JSON endpoint, reusing the same from, to, subject and html fields.

// POST https://api.mailgun.net/v3/YOUR_DOMAIN/messages
const form = new URLSearchParams({
  from: "Acme <hello@yourdomain.com>",
  to: "user@example.com",
  subject: "Welcome aboard",
  html: "<p>Thanks for signing up!</p>",
});
const res = await fetch("https://api.mailgun.net/v3/YOUR_DOMAIN/messages", {
  method: "POST",
  headers: {
    Authorization: "Basic " + btoa("api:key-xxxxxxxx"),
    "Content-Type": "application/x-www-form-urlencoded",
  },
  body: form,
});

// POST https://api.sendhiiv.com/api/v1/messages — same fields, JSON body
const res = await fetch("https://api.sendhiiv.com/api/v1/messages", {
  method: "POST",
  headers: {
    Authorization: "Bearer shv_xxxxxxxx",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    from: "Acme <hello@yourdomain.com>",
    to: "user@example.com",
    subject: "Welcome aboard",
    html: "<p>Thanks for signing up!</p>",
  }),
});
