I find their support team to be very responsive to issues. I also enjoy the monthly reports as to how our mail is performing, this provides a lot of value to my team. Lots of flexibility in the tool making it easy for it to mean our needs Review collected by and hosted on G2.com.

We primarily use the API integration so I found it difficult to implement but I felt that we had the support we needed and now that the initial set up is done its easy to use Review collected by and hosted on G2.com.

Excellent customer service and notification of when they are making changes to any of their systems ahead of time. Review collected by and hosted on G2.com.

The only real complaint i have is the lack of history on templates. So if someone makes a blunder there is no history to rollback or know who/when exactly it happened. Review collected by and hosted on G2.com.

Email sending and customization, ability to embed pictures that are responsive Review collected by and hosted on G2.com.

Would like more monitoring. Would like to use markdown. Review collected by and hosted on G2.com.

webhooks, easy interface (API), reporting and anaytics Review collected by and hosted on G2.com.

We are still implementing and have not run into any issues. Review collected by and hosted on G2.com.

The volume of emails that can be sent with SparkPost is truly impressive -- 100,000 emails per month at no charge! This alone makes it worth trying at the very least.

I found it exceedingly easy to set up SparkPost to work with my website. The web interface is clean and simple, and the documentation was surprisingly great when I needed additional help. Checklists in the web interface ensured that I had set up all of the DNS records correctly, and the ability to quickly send a test email provided peace of mind that I had actually set up everything correctly.

Another minor but appreciated feature of SparkPost is two-factor authentication through any app like Google Authenticator or Authy. While minor, implement two-factor authentication makes me feel more secure in trusting SparkPost with the ability to email all of the users of our products. Review collected by and hosted on G2.com.

I have not yet run into anything I've disliked about SparkPost. Review collected by and hosted on G2.com.

After the news about Mandrill & MailChimp integration, we were looking for another mailing service that will meet our needs and found SparkPost. These guys definitely know what they are doing.

We integrated it with OWOX BI service and now I use it for all my email marketing needs.

What I can say:

- It is packed with good real-time analytics and intuitive interface;

- Due to high daily mail limits, so there's no problem in testing templates and checking campaigns;

- Performance and delivery rates are also great;

- The amount of data it provides over hooks is overwhelming;

- It is well documented, and the solutions to issues are quite easy to implement.

By far I didn't have any critical issues with it and failed none of my campaigns. Review collected by and hosted on G2.com.

Before integrating the webhooks, Message Event reports were a mess due to 1000 results limit.

If you lost the API key, just live with it, you will never see it again =) Review collected by and hosted on G2.com.

Solid overall mta seems to do exactly as expected Review collected by and hosted on G2.com.

Not much, like I said a solid mta that does what asked. Review collected by and hosted on G2.com.

it free for teams which send low levels of emails, has a good number of ways to connect to your app just like Mandrill.

For me the main issue was pricing. Mandrill suddenly started kicking out free customers and I needed something similar and SparkPost was the best alternative that I could find. Review collected by and hosted on G2.com.

There is nothing much to dislike about SparkPost. it offers the same number of features as Mandrill and a decent quota at the moment. Review collected by and hosted on G2.com.

They are one of the leading email delivery system online. Offering some amazing features you might consider to think about. White label domain, API access, spam word detection any other features here. I mentioned "Authentic" because they are very awake about every single delivery. You can't use any fake header information on your email made them Authentic. They are restricted because system will reject any emails not sent from your domain name. It's pretty great service yet sometimes you may not like. For example , you want to deploy emailing on your cellphone app, here lot of drama using SparkPost for this service. Because your email been not sending from your domain name.

But yes they are Authentic so you can trust their delivery. Review collected by and hosted on G2.com.

As I mentioned before the only thing I didn't liked is domain restriction. Yet they offered few solution for this but I will always vote for the easiest. I have to be honest, they are amazing and trust worthy email delivery service. Review collected by and hosted on G2.com.
