Amazon SES vs Mailgun: Which is Better in 2026?
Amazon SES and Mailgun are both transactional email services, but they sell different things. Amazon SES is bare-bones email infrastructure at rock-bottom prices (~$0.10 per 1,000 emails) — raw sending you wrap with your own tooling. Mailgun is a managed email platform that bundles deliverability optimization, validation, analytics, and support on top of reliable sending, so you get a complete product rather than just a pipe.
The real trade-off isn’t the sticker price — it’s how much you’re willing to build and operate yourself. SES wins on raw per-email cost; Mailgun wins on everything around the email. Below: pricing & true cost, deliverability, what you build vs get, support & control, and how to choose.
Quick verdict
Pick Amazon SES when raw cost at scale is paramount and you can build (or already have) the surrounding tooling — bounce/complaint handling, suppression lists, dashboards, warmup, and deliverability monitoring — especially if you’re already on AWS. Pick Mailgun when you want deliverability, analytics, validation, and real support included out of the box, and you’d rather not build email infrastructure yourself. In short: SES for cheapest raw sending with DIY everything, Mailgun for a managed platform where the engineering is done for you.

Amazon SES vs Mailgun: The Details That Matter
01Pricing & true cost
On headline price, SES is unbeatable — around $0.10 per 1,000 emails, often roughly 7x cheaper than Mailgun on paper (e.g. ~$10 vs ~$75 for the same volume), with a free tier of 3,000 messages/month for new AWS accounts’ first year.
But the honest cost includes engineering: with SES you build bounce processing, complaint handling, suppression lists, webhooks (often via Lambda), dashboards, alarms, and deliverability monitoring yourself. Factor that labor in and Mailgun’s managed approach (from ~$35/month for 50,000 emails) is frequently more cost-effective overall.
SES wins raw per-email cost (~7x cheaper on paper); once you price in the tooling you must build, Mailgun is often cheaper in total.
02Deliverability
Mailgun is built around deliverability — inbox placement — with validation, reputation monitoring, and deliverability analytics to help your mail actually land in inboxes, not just leave the server.
Amazon SES focuses on delivery: it reliably hands your email off, but optimizing inbox placement (warmup, reputation, monitoring) is largely on you. For teams without deliverability expertise, that gap matters.
Mailgun actively optimizes inbox placement (validation, reputation, analytics); SES reliably delivers but leaves deliverability tuning to you.
03What you build vs what you get
SES provides raw infrastructure with the most configurability — IP pools, custom MAIL FROM, CloudWatch integration — but you assemble the analytics, bounce handling, and dashboards around it.
Mailgun ships those as product: detailed analytics, email validation, inbound routing, and optimization tools are included, so a developer is productive quickly without building supporting systems.
SES is raw, highly configurable infrastructure you build around; Mailgun includes analytics, validation, and routing as a finished product.
04Support & control
Mailgun gives you access to real deliverability engineers and 24/7 assistance across its paid plans — valuable when mail starts landing in spam and you need help fast.
Amazon SES offers virtually no live email support unless you’re on AWS enterprise support tiers, but it gives you the deepest infrastructure control and tightest AWS integration in return.
Mailgun includes real deliverability support 24/7; SES has minimal support but maximal AWS-native control.
05How to choose
Choose SES if you want the lowest possible per-email cost at scale, you’re comfortable building the surrounding tooling, and you’re already invested in AWS.
Choose Mailgun if you want deliverability, analytics, validation, and support handled for you, and you’d rather ship features than operate email infrastructure. For many teams the managed path is cheaper once engineering time is counted.
