Sinch Mailgun vs. SparkPost (discontinued)

Mailgun's pay-as-you-go pricing structure is fantastic, especially if you don't need to send that much email. The pricing, including the free tier, is much more generous than what you can get with some pricier providers, like SendGrid. I mainly just use Mailgun as an SMTP server for web services, and the service has been set-up-and-forget, which is great because I never even have to log onto the Mailgun website and do any work. Mailing list support also looks great for rolling-your-own and not relying on more expensive mailing list services.

Our early experiences with SparkPost were great; we were looking for a low-cost (or no-cost) solution to our email messaging needs, and SparkPost had the best low-cost option: 100,000 messages per month for free, guaranteed for life. Even though our team has experience with other APIs, we chose SparkPost because it felt like the best value. Our experience with it was great. Two years ago, they discontinued their free option but sent the existing users the following message: "When you signed up, we promised that if we ever changed the terms of our 100K free plan, we would continue to honor the original plan for the life of the account. I would like to reaffirm this promise: while this plan is no longer available to new customers, you are grandfathered into this level of free sending volume." The following year, apparently following a change in leadership, they decided to "deprecate" existing free plans, dropping us down from 100,000 messages per month to 500, the lowest of any email API service I'm aware of. No recognition of the broken promise, the reneged guarantee, just a 20% off coupon. This atrocious behavior that reeks of a new culture of squeezing as much money as possible out of its users and has coincided with a steady deterioration of functionality and customer service. At this point, I have no idea why anyone would pay more for a worse service that treats its users so poorly when you could use SendGrid or a similar competitor for a lower price and way more features.

• Its SMTP is very easy to use and it integrates easy with all CMS and frameworks.
• It allows you to have a record of the incoming/outgoing emails and get useful statistics about them.
• Thanks to their 5000 free emails per month, it is a very good option to startups and small companies.

Incentivized

• When you don't want to spent time writing your own code to send emails from your apps
• When you're looking for a product which provides all that you need regarding email features to make it part of your software
• When you want to use a product which includes templates that can be re-used instead of writing your own and all the required effort to do that

Incentivized

• No built-in templating features (This was a bit sad after coming from Mandrill which excelled at this)
• Dashboard UI (although easy to use) is a bit dated in appearance
• Logs are cumbersome compared to Mandrill
• Setting up TLD (top level domain) names (things like .online or .church) that are not common require an email to tech support (this is annoying)
• Sometimes can be slow in delivery
• Shared IP addresses can be SPAM filtered or delayed (requires an email to support to have a new one assigned - Note: this can be mitigated by buying a dedicated one for a monthly fee)

• When I first implemented SparkPost, I did not take advantage of the sub-account feature, and my account was suspended on New Year's Eve. It took two days until I could speak with a support representative to get my account re-activated. I am now using sub-accounts to alleviate the underlying problem, but I was disappointed that my account was suspended by an automated system with no notice.

The time for the initial setup is very quick, since you can start sending (thus developing) from their sandbox in no time. The actual configuration involves, as usual, some DNS changes that may require time but are well explained and documented. Once everything is set up, there are a lot of monitoring tools that you can use to optimize your lists.

There have been a few minor outages through the years, but nothing more than a few minutes. These small outages are to be expected in any kind of a SaaS product, but Mailgun handles them very well. We designed our software to just retry sending after a while if there is an outage. As far as I know, we have never had to do more than a few retry cycles. This is all automated on our end, so we rarely even notice. Our customers have never noticed any mail sending outages.

The API and the deliverability of emails is excellent. Their API is very responsive and performs perfectly fine. I have no complaints there. Their management interface though (accessed through the web) is pretty slow though. Searching through lists of emails when I'm tracking down a problem for a customer can take 10+ seconds which is annoyingly high for a modern web app.

You can't seem to get ANY support until you shell out hundreds of dollars per month. I even did this when we could not deliver mail with Mailgun, and the response was slow and inadequate. Nor would they refund my money. I'll never be a customer of Mailgun again.

Would give it a zero if I could. Their customer service used to be incredible; fast response times, really hands-on with their users, and a pretty regular feedback process. They sent me an awesome t-shirt that became part of my go-to climbing gear. But for the past year, their response times went way down, their customer service was less helpful and generally a lot more rude, and they haven't asked for customer input once since their leadership change

To be honest, the tools are quite similar and again I dont recommend using them as a standalone products, but they power the work we do via CRMs and our marketing campaigns. Mailgun integrates slightly better which it is why it is the preferred choice for our agency, as it integrations options seem to be better

Mailchimp and sendgrid are giving good services and good customer support 24/7 and ROI is increased with this as transition is very smooth. SparkPost is very expensive and not good as much as we think and they will least worried about your mails, tickets, call and messages. Highly not recommended this SparkPost to any one

Over the past six years, Mailgun has scaled with our growth very easily. We haven't had to make any code changes to handle our larger volume today, and their pricing has scaled naturally with our growth. As far as I know, there is nothing we will need to do in order to grow 10-fold. Mailgun just handles the load really well.

Incentivized

• By not investing in our mail server, we have saved huge amount of money and time. For configuration and installation of an email server on Linux-based server, we would have to hire a network administrator.
• If email delivery is an issue in a hosting provider, another solution is to switch the hosting. Fortunately with Mailgun, we didn't need to try different hosts and experiment which one works best for emails. We can stick to our existing web hosting provider and would not need to change it just for the sake of improving email deliverability.
• The pricing of Mailgun is very cheap and straightforward. First 10K emails are free every month and that's a big advantage for our organization because our volume of emails is rarely more than 10K per month.

Incentivized

• It has helped us with our IP health and making sure that we avoid spam traps
• Very high deliverability and automatic retrying once they have the event
