Key takeaway
Mailgun is a developer-focused email API built for transactional sends. mailtani is a complete email platform built for founders and bootstrappers who want sequences, warmup, and BYOS without an open-ended monthly bill.
- Pricing model: $35–$90/month base + per-email overages vs mailtani's €89 one-time
- Dedicated IPs cost $59/month extra on Mailgun — included via SES on mailtani
- Mailgun is transactional-only; mailtani adds sequences, warmup, rotation, and broadcasts
- mailtani suits bootstrappers and founders; Mailgun suits developer teams needing raw SMTP/API
Mailgun's overage model means every growth milestone costs more. At 200k emails/month on Foundation, you pay $155 — that's $1,860/year and climbing. And the bill only covers transactional sending. Marketing sequences, warmup, and inbox rotation all require separate tools.
- Monthly base fee plus $0.80/1,000 overage emails — costs compound with growth
- Dedicated IPs cost $59/month extra — not included on any standard plan
- No marketing sequences, broadcasts, or campaign builder at any tier
- No email warmup or inbox rotation tooling
- No bring-your-own SMTP — locked to Mailgun infrastructure
- Shared IPs on Foundation — reputation affected by other senders

What Is Mailgun?
A developer email API with growing per-email overages and no marketing features built in.
Mailgun has been a developer staple for transactional email since 2011. Acquired by Sinch in 2021, it handles the reliable plumbing of web applications — password resets, order confirmations, notifications via a clean SMTP relay and REST API. For teams that need raw transactional infrastructure, it works.
The pricing model is where the friction starts. Mailgun charges a base monthly fee plus per-email overages above the plan limit. On Foundation ($35/month), you get 50,000 emails — then $0.80 per 1,000 after. A SaaS app sending 200,000 emails per month pays $35 + $120 = $155/month, or $1,860/year. Every growth milestone drives the bill higher with no ceiling.
What Is mailtani?
A one-time purchase email platform for founders, indie hackers, and small SaaS teams.
What Mailgun does not provide is equally important. There is no marketing campaign builder, no sequence editor, no email warmup, and no inbox rotation. Founders who want to send newsletters, onboarding sequences, or outreach campaigns need a separate platform on top of Mailgun. Dedicated IPs — which you need for isolated deliverability — cost an extra $59/month, not included in any base plan.
mailtani replaces the entire split stack. Connect your own AWS SES account at $0.10/1,000 emails — nearly 8x cheaper than Mailgun's overage rate — and get sequences, broadcasts, warmup, and inbox rotation included for a €89 one-time payment. For founders who want their full email operation in one tool without open-ended monthly costs, the math is straightforward.

Why Users Switch from Mailgun
The common reasons teams move on.
- Overage fees mean no cost ceiling: Mailgun charges per email above your plan limit. As your SaaS grows and sends more — onboarding flows, notifications, broadcasts — the bill climbs with it. There is no point where costs plateau.
- No marketing features anywhere in the product: Mailgun is purely transactional infrastructure. Sequences, broadcasts, contact lists — none of it exists. Every founder who wants marketing email on top of Mailgun ends up paying for a second platform, doubling their monthly costs.
- Dedicated IPs cost $59/month extra: For isolated sending reputation, you need a dedicated IP. On Mailgun, that is $59/month on top of your base plan. For a bootstrapped founder who wants deliverability control from day one, that premium is hard to justify.
- No warmup tooling for new domains or IPs: When you add a new sending domain or dedicated IP, Mailgun provides no warmup automation. You manage that process manually — a technical task that is easy to get wrong and directly impacts inbox placement.
- Locked to Mailgun infrastructure with no BYOS option: You cannot connect your own AWS SES key. Your sending reputation lives on Mailgun's infrastructure, which you share with other senders. There is no way to move it without switching platforms entirely.

What You Get With mailtani
The features founders and indie hackers actually use — on your own infrastructure, for a one-time payment.
Bring Your Own SMTP
Connect your own AWS SES, Resend, or Mailtrap account and send at infrastructure cost. Your sending reputation is entirely yours — not pooled with other users on shared IPs.
Email Warmup
Automatically ramps up your sending volume over 3–6 weeks, building genuine sender reputation with Gmail and Outlook. Set it once — mailtani handles the daily schedule without a separate tool.
Inbox Rotation
Distribute sends across multiple inboxes automatically to protect deliverability and scale volume without burning a single sending address. No manual scheduling required.
Sequences and Drip Campaigns
Build multi-step email sequences with conditions, delays, and branching logic. Welcome flows, onboarding drips, and re-engagement campaigns all run on the same builder.
One-Time Flat Pricing
Pay €89 once. No monthly fees, no per-contact tiers, no price increases as your list grows. Whether you have 500 or 500,000 subscribers, the cost is the same: done.
Full Deliverability Control
Sending reputation, IP addresses, authentication records, and SMTP credentials all belong to you. Diagnose and fix deliverability issues directly rather than waiting on platform support.
