Nuntly vs Mailgun
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 uses form-encoded requests (not JSON), has no TypeScript SDK, no idempotency keys, and unclear email events
- Nuntly adds fast API latency, a modern JSON API, unified deep-stack observability, idempotent requests, and EU data hosting by default
- Mailgun is expensive at scale, EU data is only partially regional (API keys and billing stay in the US), shared IP pools can be noisier, and there is no template system
Why developers choose Nuntly over Mailgun
The differences that matter most when choosing an email platform.
Cost effective pricing
Bootstrap company with cost effective pricing at every volume tier. No noisy shared IPs, no slow support, no surprise price increases.
Complete inbound email API
Nuntly provides full inbox management, thread grouping, message storage, and a reply API out of the box. Mailgun inbound routes require you to build inbox logic yourself.
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.
Fast API send latency
Optimized for speed at every volume tier. No form-encoded overhead slowing down your API calls.
Feature by feature
A side-by-side look at what each platform offers.
Nuntly
Mailgun
Cost Effective
Both platforms offer permanent free tiers with about 3,000 emails/mo. At scale, the gap widens: 100k emails/mo costs from €28/mo (Nuntly) vs $75/mo (Mailgun). 500k emails/mo costs €265/mo vs $400/mo. Nuntly is a bootstrap company with no VC-driven price pressure.
Mailgun increased its Flex plan pricing from $1.00 to $2.00 per 1,000 emails in December 2025.
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. Event replay is included on all plans to recover from any missed webhook.
Security
Mailgun separates data into "Global" (account info, user accounts, billing, API keys) and "Regional" (messages, event logs, routes, suppressions). Selecting the EU region only covers operational data. Account and billing data always stay in the US. Nuntly stores all data in Europe by default on every plan, with no global spillover.
Developer Experience
Mailgun's API uses form-encoded requests by default with inconsistent endpoint patterns across features. SMTP requires custom headers for basic features like tags. Email events are not clearly structured. Nuntly uses JSON everywhere with a consistent API design and full API request logs.
Advanced SDKs
Mailgun lacks a TypeScript SDK and has no official SDKs for Python, Rust, or .NET. No idempotency key support increases the risk of duplicate sends during network failures. Nuntly provides fully typed SDKs with built-in retry logic and idempotent requests out of the box.
Deliverability
Both platforms cover the fundamentals: DKIM, SPF, DMARC, and suppression lists. Many users report that Mailgun shared IP pools can be noisier. Nuntly focuses on transactional only, keeping shared IP reputation cleaner.
Email Sending
Both support scheduled delivery, bulk sending, and flexible content formats. Mailgun has no template system.
Email Receiving
Mailgun Routes POST a massive JSON payload to your webhook (full email body, attachments in base64, raw MIME headers). Behind that checkbox is a basic forwarder: you are now responsible for parsing the payload, decoding attachments, persisting messages, handling duplicates, and scaling your own load balancer to absorb incoming email traffic. Nuntly handles all of this for you: storage, threading, inbox management, and a REST API to access everything.
API Performance
Nuntly is optimized for fast API send latency, which matters for high-throughput applications where every millisecond counts.
