Mailgun is a reliable email delivery platform that makes it easy to send both transactional and marketing emails. I appreciate its developer-friendly features, straightforward integration, and the helpful analytics that let me track email performance. Overall, it feels like a solid option for businesses that need dependable email delivery along with clear monitoring and visibility. Review collected by and hosted on G2.com.

What I dislike about Mailgun is that some of its more advanced features and settings can take a while to understand, especially for new users. The pricing can also feel a bit complicated, depending on the volume of emails being sent. Review collected by and hosted on G2.com.

The online help we required when building API calls from our software was easy to access, clear and accurate. We are now guiding clients to using MailGun themselves! Review collected by and hosted on G2.com.

I can never find where I set the IP addresses to accept calls from! Review collected by and hosted on G2.com.

I use Mailgun for all our automated reports, welcome invites to users, and even password reset emails. What I like most about Mailgun is its simplicity. Their deliverability is incredible, especially when compared to our other more marketing-based email system. The initial setup was very easy and it's built for easy development. Mailgun handles all of these emails for us, so we don't have to manually manage them. The logs are also incredibly well done, making it easy to go back and find any issues with why emails aren’t being sent. Review collected by and hosted on G2.com.

Not much. I'm being nitpicky here, but when you're on a large monitor, and you want to add filters to your logs that you're looking through, because the filters show on the far right, it's just a little weird to me. Like I look at the left, click the filter button, to have them show on the right. Not that bad, like I said, being nitpicky Review collected by and hosted on G2.com.

Very easy to set up, with a variety of SDKs to integrate into my codebase. It also has a rich dashboard for tracking emails and creating custom HTML templates. Review collected by and hosted on G2.com.

Pricing and feature limits can become confusing as usage scales, and some advanced configurations have a learning curve for new users. Review collected by and hosted on G2.com.

It is very easy to setup, they build quite simple step by step interface for that, even have integration with CloudFlare to add DNS records automatically. Deliverability graph is done simple and nicely, shows failed emails right away as well. Review collected by and hosted on G2.com.

One time integration with CloudFlare didn't work for some reason, it said try in couple minutes again but was down at least for an hour so I had to manually add records. Otherwise everything was fine. Review collected by and hosted on G2.com.

We like Mailgun's very clean UI/UX, which makes it easy to use. It's reliable with 100% uptime. The API is easy to implement, and I appreciate that it also offers an SMTP option. We switched from Amazon SES to Mailgun because of the better UI and fewer deliverability issues. The initial setup of Mailgun was very easy, taking just a few minutes. We also like that Mailgun can be connected to many other software, such as Iterable. Review collected by and hosted on G2.com.

Setting up tracking can be a bit complex depending on how you manage your SSL certificate and if it allows multi-level subdomains. Also, logs can be fairly complex to navigate, it always takes a lot of time to find a specific email, there's no easy search feature. Review collected by and hosted on G2.com.

Mailgun has proven to be highly reliable for sending transactional emails and system notifications. Its API is thoroughly documented, simple to integrate, and offers the flexibility needed for more complex scenarios. I have consistently experienced strong deliverability, and the inclusion of features such as logs, webhooks, and event tracking greatly simplifies debugging and monitoring email performance. Setting up DNS is uncomplicated, and authentication methods like SPF, DKIM, and DMARC are well supported. Review collected by and hosted on G2.com.

As your usage increases, the pricing model can become quite costly, which may be a concern for smaller teams or startups. Although the UI is functional, it appears outdated in certain sections and may be challenging for users without a technical background. Additionally, accessing some advanced features often requires searching through documentation, as they are not always prominently displayed within the dashboard.

The best thing about Mailgun is its ability to handle high sending volumes reliably while protecting our domain's reputation.

As a commercial SME, we send a lot of electronic documentation, and before using Mailgun, our domain was constantly being blocked due to high bounce rates and invalid emails.

Mailgun automatically manages and filters these issues, which is crucial for our operations. The fact that they control the 'messy' side of email sending means our critical documents always get delivered, and our domain is safe. Their fast support is also a major plus.

Honestly, once it’s set up, there's not much to dislike because it just works.

If I had to pick something, I'd say the initial setup and interface can be a little confusing. Getting the DNS records and the API integration done was complicated for a small company like ours that doesn't have a full IT team. It felt very technical at first.

It would be great if they had a super simple "Setup for Business Owners" guide, not just the technical docs. But again, once you get through that initial hurdle, it’s excellent. Review collected by and hosted on G2.com.

I love Mailgun's one-line API send, which means I can add just 5 lines of code and all my emails keep working forever without any server config issues. The templates and variables are amazing because I don't have to hardcode anything like “Hey {{name}}” again, which saves me hours every week. Batch sending is a huge plus as I can send 10k personalized emails in one call, completing the task in seconds rather than hours. The real-time webhooks are fantastic; they auto-clean the list the second an email hard-bounces, helping me avoid losing money on dead emails. Inbound routes are incredibly helpful because they automatically create tickets when customers reply, making me look professional without extra effort. Auto suppressions are a lifesaver, preventing me from accidentally spamming anyone who has unsubscribed or bounced, which preserves my sender reputation. The one-click unsubscribe handling is a big win, reducing angry replies and keeping my support inbox manageable. I appreciate the searchable logs that let me verify delivery quickly, often ending conversations within 30 seconds. The free sandbox domain for testing is also great because I can test every email flow right away without buying a domain. The two-click DKIM/SPF/DMARC setup is really convenient, and having a dedicated IP when I grow helps with scalability. Review collected by and hosted on G2.com.

{"Sudden account suspensions without warning – I wake up to my entire email flow dead because their bot flagged 'suspicious activity' (even on legit transactional stuff), and support ghosts me for days while users flood my DMs saying 'where's my reset link?!' Total trust-killer.","Pricing ramps up way too fast once I grow – Starts cheap for my MVP, but hit 50k emails/mo and bam—$35 base jumps with overages, plus dedicated IPs at $90+? I feel nickel-and-dimed when I'm just trying to onboard more users without rewriting my code.","Free tier got gutted and feels useless now – Used to be a lifesaver for bootstrapping, but now it's 30 days/5k emails then throttles hard to 300/day with 1-day logs only. I outgrew it in week 2, forcing me to pay sooner than planned.","Setup and dashboard scream 'dev-only' – No wizard for domains/DNS—I’m pasting TXT records at 2am and hoping I didn’t typo. The UI is clunky for quick checks; I end up in API docs more than the dashboard, which slows me down when I’m iterating fast.","Deliverability hiccups to Outlook/Hotmail – Gmail/Yahoo are fine, but 20-30% of my Microsoft users never see password resets or alerts. Their 'warm-up' advice is vague, and I waste hours tweaking content just to chase inbox placement.","Support is email/ticket roulette – No live chat or phone unless I'm on the $90 plan. A bounce spike or webhook glitch? I submit a ticket and stare at 'under review' for 48+ hours while my churn ticks up. Phone support as a paywall feels punitive.","Logs vanish too quick on basics – Free/basic plans keep logs for 1-3 days only—user complains 'I didn’t get the invoice' a week later, and I have zero proof to debug. Forces me to build my own archiving, which is dumb.","No built-in marketing tools or pretty templates – I'm stuck coding simple HTML for promos or 'trial ending' nudges, then pairing with Mailchimp for anything drip-y. Why not bundle basics so I don't juggle two dashboards?","Occasional outages or delays I can’t predict – Rare, but when their API hiccups (like that global queue issue last month), my whole signup flow breaks. No real-time status page alerts—I'm scrambling via Twitter instead of building."} Review collected by and hosted on G2.com.
