6

Account Suspension Without Warning

high compliance

Multiple users report having their accounts permanently disabled without specific reasons given, often after upgrading to paid plans. This can cause significant business disruption, especially for time-sensitive use cases like 2FA or password resets.

trustpilot

Today, while trying to send a legitimate mailshot for a UK business, I ran into account limits and contacted support straight away. My account was then put under evaluation... Shortly afterwards, they permanently disabled the account without giving any specific reason.

trustpilot

as soon as I paid to move to production, they blocked me and are holding my money for 10 business days, knowing that I paid and blocking me immediately.

7

Shared IP Deliverability Problems

critical overage

Users on lower-tier plans share IP pools with other senders. When other senders on the shared pool trigger spam flags, legitimate senders' emails get deferred or land in spam — particularly affecting Yahoo, AOL, Hotmail, and Outlook. Users report business-critical emails like 2FA codes and legal documents being delayed by hours.

trustpilot

Our transactional emails — 2FA login codes and time-sensitive legal DMV documents — started landing in spam or getting deferred for Yahoo, AOL, Hotmail, and Outlook recipients. The culprit was a shared IP (143.55.232.45) flagged by Yahoo with error TSS04 due to other senders on the pool.

hn

Yep I had the same problem years ago when I tried to use Mailgun's free tier. Not picking on them, I loved the features of their product but the free tier IPs had a horrble reputation and mail just would not get accepted especially by hotmail or yahoo.

8

Unauthorized Charges After Cancellation

high addon

Multiple users report being charged after attempting to cancel or delete their accounts, with no responsive support to resolve the billing issue.

trustpilot

Completely ignored my request to cancel, and continued billing me. Disgusted

I deleted the account and they are still charging my card.

Security Incident Liability

critical overage

When API keys are compromised and used to send unauthorized email, Mailgun charges customers for the usage even without conclusive evidence the breach was on the customer's side.

trustpilot

Our Mailgun API key was breached and used to send 3.5m crypto scam emails. Mailgun could not provide any evidence that the breach occurred on our side, and despite not fully investigating how the key was leaked, charged us over $1,000 for the usage.
