Web-based

CTO Latam

They responded 6 months latter with wrong information delaying more and more the payment, but then they cut the service. It is the worse service I have ever received.

Marketing and Communications Specialist

Overall it has tied into our system great, and we have only had a few minor issues. And the nonprofit pricing is great.

Web Developer

Their response: "I'm sorry to hear you are still unable to pass the system's address verification. We have the address verification in place to prevent fraudulent charges. A bureaucratic nightmare.

SparkPost is, in theory a very nice and slick email delivery service. They offer a fair amount of free emails each month.

We do tend to go to spam a lot and when looking at Sparkpost, the lingo is very confusing unless you have someone who understands code.

Digital Strategy Manager

The account might be suspended even you have followed their own recommendations. And if that was not enough you can't cancel your account while this is suspended.

It helps with setup, delivery, logging and tracking and it does all of it beautifully well.

Product Engineer

Onboarding was great as well as customer service which we contacted on different occasions and always got back to us in a timely manner with a helpful response.

Marketing Manager

SparkPost is a great email delivery platform with an easy-to-navigate web UI and straightforward setup. Support is quick to respond (within 24 hours) and always willing to help.

Director Customer Success

I like that it is integrated with our systems - it does work smoothly and the analytics are helpful for reviewing open, close, bounce, etc rates.

Software Developer

I liked the simplicity of setting up and the possibility to manage sub-accounts.

Creative Director

API delivery is super simple and offers SMTP server-based injection. Easy to set up DKIM and SPF.

A great tool to optimize your email functionalities.

Easy to use and implement, the tool works good.

Got flagged due to spam for having a link for acuity scheduling in a follow up sequence without even sending more than 4 test emails to myself.

If this is how they are if you're trying to GIVE them money, imagine how they must be with other problems.

Postmark

I use the SMTP integration to send administrative alerts from my web servers. I appreciate the reliability of deliverability for these critical messages. I prefer to offload the responsibility of sending email from my web servers so they can do the job of hosting. The other benefit I get is that my SPF and DKIM settings can be static for all domains I host instead of tying my sending IPs to my hosting IPs, which have the possibility of changing.  I can also easily whitelist delivery of my admin alerts to make sure I receive critical information instead of it accidentally being sent to spam.

Bulletproof API mail delivery with OK freemium tier

My experience with SparkPost was very good. It is a highly reliable email delivery service.

SparkPost Review: Delivering Emails with Precision.

Sparkpost & MessageBird are irresponsibles with their account suspension, they don't care about the impact they can produce to the customers, and they don't care about the service. They cut our service because they didn't answer to more than 25 emails and 15 tickets we opened to inform that we need the payment information which they changed when moved from Sparkpost to MessageBird. They responded 6 months latter with wrong information delaying more and more the payment, but then they cut the service. It is the worse service I have ever received.

Sparkpost & MessageBird are irresponsibles

Good service to make sure your emails will arrive where they should

Great, generous offerings for users grandfathered into their 100k free plan

Glad you're enjoying the service! We do not plan on un-grandfathering anyone who took advantage of the 100K free plan back in 2016. But we do want you to be successful, so hopefully your business will grow and you'll be sending a lot more than 100K emails/month eventually. Best of luck and Happy Sending! 

I can only warn anybody who relies on their mail being sent to use sparkpost.
We used sparkpost for more than two years. It seems that several months ago they added some automated abuse detection which flagged our account. We only use sparkpost to send transactional mail to our customers and do not send unsolicited marketing mails or similar.
When our account got suspended we couldn't reach anybody to fix this for hours. After finally getting into contact our account got activated again and we just received a standardised "Sorry" E-Mail and that's it.
 We haven't had the resources to switch out our mail provider and now after 6 weeks our account got suspended again. After not being able to reach somebody for hours, the person we got in contact with only told us that some other department was responsible for account suspensions.

This service absolutely terrible and you definitely do not want this as a critical part in your architecture. 

Not a service you want to rely on

Hi Bernhardt, thank you for taking the to leave this review. In order to protect all of our senders against potentially bad actors or bad sending practices that would affect sending pools, we have a strong Messaging Policy that we enforce posted on our website (https://www.sparkpost.com/policies/messaging/). If you feel this does not apply to you, you can always write in to compliance@sparkpost.com to try and remedy the situation. Thanks again and have a wonderful rest of your week!

It was great until it went to complete garbage. The lack of communication about the suspension and then their unwillingness to help resolve the issue, is ultimately what resulted in such a terrible review. And now I get to spend more time moving clients to another service at my cost.

Don't use for Wordpress

Our user verification and engagement is powered by SparkPost

 The Sparkpost team is clearly committed to improving their product, and they care about their customers. For anyone who's happy to use the API for configuration, using Sparkpost is a no-brainer.

Can't beat the price, but usability could be improved

Sparkpost - solves key email challenges

Their new nickel-and-diming approach speak to new management or bad prioritization, squeezing every dime they can out of their customer base instead of focusing on the product. The product is getting worse while the prices are going up. And if they lied about past agreements, they're likely to do it again. I'd go elsewhere if I were you.

Can't be trusted

Worst Customer Service Ever

We are terribly sorry we couldn¿t get this resolved, it is an edge case limitation within our current payment infrastructure in the UK and we are actively looking to get this addressed so everyone can take advantage of the SparkPost service. We appreciate the feedback.

Great experience using SparkPost for our offices outbound email needs!

Best and Most Affordable SMTP Service

We use this on all our projects to handle transactional emails, this has definitely been a useful software, it's great all round but event webhooks that are domain specific would be great 

Great Transactional E-mail service that get the job done

Thanks for your review and your feedback! We have passed along your suggestion to our product team. Would you be willing to chat with them for further feedback?

When it works it works great

We use SparkPost on many bigger projects and I would recommend it for projects where mass emailing is a priority.

A great tool to optimize your email functionalities

Poor service 

Hi Adam, I'm sorry to hear about your experience. In order to protect all of our senders against potentially bad actors or bad sending practices that would affect sending pools, we have a strong Messaging Policy that we enforce posted on our website which prohibits affiliate marketing, and which is why you were suspended. (https://www.sparkpost.com/policies/messaging/). If you feel this does not apply to you, you can always write in to compliance@sparkpost.com to try and remedy the situation. 

We inherited the tool from another product team, and it is very integrated, so hard to remove - but also does work well in the sending of our automated emails.  There is very little down time which is great. We wish the filtering was less cumbersome/sensitive and that there was a larger window for seeing past emails than 10 days. 

Good, but some features hard to view

Full-featured API-first ESP with great support

Accounts get suspended without warning or notifications

Perfect for sending transactional mail using WordPress

A good tool with poor criteria and bad customer service
