Looking for a Mailgun alternative?
Fast API send latency, deep-stack unified observability, EU data hosting by default, and cost effective pricing. No form-encoded requests, no noisy shared IPs.
Free plan available. No credit card required.
Mailgun was founded in 2010 and acquired by Sinch in September 2021. It remains a capable email platform, but its form-encoded API, noisy shared IP pools, lack of idempotency keys, unclear email events, and expensive pricing at scale push developers toward modern alternatives. Nuntly is built from the ground up with fast API latency, unified deep-stack observability, and EU data hosting by default.
- Mailgun is a mature platform with email validation and routing features but carries form-encoded API patterns from 2010
- Nuntly adds fast API latency, unified deep-stack observability, idempotent requests, and EU data hosting by default
- Mailgun is expensive at scale and its shared IP pools can be noisier. Support is slow unless you are on a high-tier plan
Why developers choose Nuntly over Mailgun
The differences that matter most when choosing an email platform.
Fast API send latency
Optimized for speed at every volume tier. No form-encoded overhead slowing down your API calls.
Unified deep-stack observability
API logs, email flow, delivery events, and webhooks in a single unified view with clear email event tracking. Mailgun email events are not clearly structured and there are no API request logs.
EU data hosting by default
All data stored and processed in Europe by default. No opt-in region selection required. Full GDPR compliance on every plan.
Cost effective pricing
Bootstrap company with cost effective pricing at every volume tier. No noisy shared IPs, no slow support, no surprise price increases.
Feature by feature
A side-by-side look at what each platform offers.
Nuntly
Mailgun
Deliverability
Both platforms cover deliverability fundamentals. Mailgun has a mature infrastructure, but many users report that its shared IP pools can be noisier than other providers. Nuntly focuses exclusively on transactional email, which keeps shared IP reputation cleaner.
API Performance
Nuntly is optimized for fast API send latency, which matters for high-throughput applications where every millisecond counts.
Advanced SDKs
Mailgun lacks a TypeScript SDK and does not have official SDKs for Python, Rust, or .NET. It also does not support idempotency keys, increasing the risk of duplicate sends during network failures. Nuntly provides fully typed TypeScript and Java SDKs with built-in retry logic and idempotent requests out of the box.
Developer Experience
Mailgun's API uses form-encoded requests by default and has inconsistent endpoint patterns across features. Email events are not clearly structured, and you need to send custom headers in SMTP for basic features like tags. Nuntly uses JSON everywhere with a consistent, predictable API design and full API request logs.
Security
Mailgun offers EU hosting, but it requires selecting the EU region during setup and is not the default. Mailgun does not offer Google or GitHub as authentication methods. Nuntly hosts all data in Europe by default on all plans, with modern authentication options.
Observability
Mailgun provides aggregate stats and webhook delivery, but email events are not clearly structured and there are no API request logs. Nuntly provides a unified view of API logs, email flow, delivery events, and webhooks in a single place, with event replay on all plans to recover from any missed webhook.
Cost Effective
Both platforms offer permanent free tiers with about 3,000 emails/mo. The key difference is cost at scale: at 100k emails/mo, Nuntly costs from €28/mo vs Mailgun $75/mo. At 500k emails/mo, Nuntly costs €265/mo vs Mailgun $400/mo. Nuntly is a bootstrap company with cost effective pricing and no VC-driven price pressure.
Sending Capabilities
Core sending capabilities are equivalent. Both support scheduled delivery, bulk sending, and flexible content formats. Mailgun also handles inbound email routing, which Nuntly does not offer.
