Customer.io

If you have a very small database of people, then probably the whole integration isn't justified. If you have a small business and don't plan to scale much, don't do it. It will be expensive for what you can get elsewhere (Mailchimp).If you want a scalable and powerful platform, that will take some time to pay off, and you can wait, then do it. Once you get integrated and start sending events and attributes, the things you can do are almost limitless.

Sailthru

Sailthru is well suited for any company that is working with a large email subscriber list and needs to send campaigns on a daily basis. It is probably less appropriate for anyone with a small list, or an e-commerce brand. I think there are better ESPs out there for e-commerce brands.

Pros

Customer.io

  • Workflow building and management.
  • Extremely flexible and integrates easily with other services.
  • Solid email builder.
  • Webhook makes it easy to send and receive data in event-driven contexts.
  • Support for liquid makes highly detailed personalization possible in every message.

Sailthru

  • Personalized content based on user behavior and content consumption.
  • Campaign workflow is very simple and allows for a large number of campaigns to be set up and managed in a short period of time.
  • Sailthru has a great customer service team. Our account support with Sailthru was top-notch and is a testament to the culture there at the company.
  • Sailthru focuses on email marketing. With all of the other "cloud" solutions out there trying to be everything to everyone, they lose focus on the importance of sending the email. This is where Sailthru shines.

Cons

Customer.io

  • I may be missing it in the UI, but a place to see the list of emails who qualify for a certain email.
  • One easy to view chart of all our automated/lifecycle emails to see what a given user would see over their customer journey. (This is really just a feature request/idea - the product itself is really awesome.)
Ted Bennett | TrustRadius Reviewer

Sailthru

  • Giving more practical examples of technical setups, sometimes the only way to understand it is to see it.
  • Can't filter lists by date created or date modified, particularly needed when tracking down a specific list or looking to remove older lists.
  • Can't set up automated data dumps to an email address, has to be sent via API.

The biggest factor is that even after two months of trying to go through their credit processes and getting the right consideration for the real damages we had with the tool not being able to send campaigns for days, their sales staff is still not willing to work with us on it, making us do the switch away from them right now. We got extremely disappointed by trying to work with them through those issues.

Their account management / sales staff doesn't seem to be taking the problems you experience very seriously - it took us 3 months and nudge emails to them every 2 weeks to ask for status updates (plus 6 different conversations with different people) to get a (very small credit) for a major issue, which in two months prohibited us from sending campaign emails for 2-3 days at a time.

Alternatives Considered

Customer.io

Customer.io was really the first pure, full-featured drip email program on the market and as far as I know, it's still the simplest and best overall for that specific function. SendGrid has also added drip campaign features, but I would seriously evaluate Customer.io against any other drip email provider because they really have all the key elements you need to make it work.

Sailthru

Sailthru is much more robust and evolved than MailChimp. That's not to say that MailChimp wasn't a great platform for us, as it dramatically helped our business grow and it's a great resource that I'd recommend to any start-up. However, Sailthru offers a different ideology more centered around automated emails and working smarter over creating batch-and-blast emails. Sailthru also is much easier to analyze than anything associated with Mandrill

Return on Investment

Customer.io

  • Fast testing for new products to specific groups. It saves a lot of time and money.
  • Removed workload from marketing = more time to make it better.
  • Better contact with specific groups, seeing a increase in sales because of this.
Mike Koolwijk | TrustRadius Reviewer

Sailthru

  • Sailthru allows us to see how well an ad in a newsletter has done by day and week -- allowing us to gift insight for our clients on their ads that ran that week.
  • Sailthru only gives you clicks and touch rates, where as other platforms go deeper and give you insight on hover rates and interaction time with our ads featured.
