    I don't work with the CRM team but I do know that they use flexEngage to track click-through rates associated with the advertising of promotions, gifts with purchase, BOPUS, etc. There's definitely a lot less information to be had from a point of sale point of view because the transaction originates there. I know it's been a great benefit to us and our customers.

    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.

    Pros
    Klarna
    • The partnership and communication with us have just been amazing.
    • They respond to change requests very quickly and turnaround time is minimal.
    • Most importantly, the resulting e-receipts look great!

    • 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.

    Cons
    Klarna
    No answers on this topic
    Sinch (formerly CLX Communications)
    • 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)

    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.

    Reliability and Availability

    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.

    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

    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.

    Return on Investment

    • None of that info is available to me at this point.

    • 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.
