Loops vs Mailgun: Which is Better in 2026?
Loops and Mailgun both send email, but they’re built for different jobs. Loops is a modern, SaaS-focused email platform that unifies transactional and marketing email with a clean API, visual editor, lifecycle automation, and subscriber-based pricing. Mailgun is developer-focused email infrastructure — a reliable sending API with validation, inbound routing, and detailed logs that you build product features around.
The split is product vs plumbing. Loops gives SaaS teams a finished email platform; Mailgun gives developers raw, programmable sending power. Below: platform scope, transactional model, pricing, developer experience, and how to choose.
Quick verdict
Pick Loops when you’re a SaaS company that wants transactional and marketing email in one modern platform — visual editor, lifecycle automation, unlimited transactional on paid plans, and subscriber-based pricing — without stitching tools together. Pick Mailgun when you want programmable email infrastructure: a reliable API, email validation, inbound routing, and granular control to build exactly what you need. In short: Loops for a unified SaaS email product, Mailgun for developer-grade email plumbing.

Loops vs Mailgun: The Details That Matter
01Platform scope
Loops is purpose-built for SaaS, combining transactional and marketing email under one roof with lifecycle workflows, a visual editor, and SaaS-specific automation. It’s a product you configure, not infrastructure you assemble.
Mailgun is fundamentally email infrastructure: a robust sending API with webhooks, logs, validation, and inbound routing — but no marketing campaigns, no visual automation builder, no lifecycle workflows, and no billing integrations. You build those yourself.
Loops is a unified SaaS email product (transactional + marketing + automation); Mailgun is raw email infrastructure you build product features around.
02Transactional model
Loops makes transactional email unlimited on every paid plan, and its Loops Events product lets you trigger transactional sends from API calls with built-in delay logic and conditional branching — so if you already use Loops for marketing, you don’t need a separate automation tool.
Mailgun’s sending API is reliable and well-documented, handling both transactional and bulk email with comprehensive webhooks, detailed logs, and per-recipient analytics — powerful programmable routing, but you wire up the lifecycle and branching logic yourself.
Loops offers unlimited transactional + built-in event/branching logic; Mailgun offers a powerful programmable API you orchestrate yourself.
03Pricing
Loops prices by subscriber count, not send volume, with unlimited sending: ~$49/month covers up to 5,000 subscribers and ~$249/month up to 50,000 — predictable as your sending grows, since adding volume doesn’t raise the bill.
Mailgun prices by emails sent per month — affordable at ~$35/month for 50,000 emails — which suits high-volume transactional senders, but you’re paying for plumbing, not a marketing/automation product.
Loops bills by subscribers with unlimited sends (predictable as volume grows); Mailgun bills by send volume — cheaper for raw high-volume sending.
04Developer experience
Loops offers a modern DX with a clean API and visual editor aimed at SaaS teams — fast to set up, with marketing and transactional unified, though it’s younger than the incumbents.
Mailgun offers a mature, well-documented API with deep logging and routing that developers who want full control appreciate — but you assemble campaigns, editors, and automation yourself since it’s infrastructure, not a product.
Loops gives a modern, unified, fast-to-set-up SaaS experience; Mailgun gives a mature, controllable API you build the product layer on.
05How to choose
Choose Loops if you’re an early- or growth-stage SaaS that wants one modern platform for transactional and marketing email, with automation and a visual editor included.
Choose Mailgun if you need programmable email infrastructure with strong routing, validation, and logs, and you’re fine building the campaign/automation layer — useful for B2B SaaS with complex transactional needs.
