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

Sailthu is perfectly suited, no matter what level of technical skill you have or support from an Engineering team. That said, it includes many advanced features which can only be fully utilized when integrated with custom webhooks and after receiving customer data sent via their APIs. There may be easier solutions out there for less technical users or for people wanting a simpler setup to begin with.

Pros

Customer.io

  • Workflow building and management.

  • 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.
Joel McLean | TrustRadius Reviewer

Sailthru

  • Personalization - one of the most important things you can utilize when emailing people.
  • Segmentation - Sailthru makes it very easy to build an audience based off their criteria; there are so many different fields to choose from. We use this mostly for geo-targeting and engagement.
  • Analytics - post-campaign analytics are very easy to look at, customize your view, and download as a csv to share with your team and company.

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 provided a powerful, easy-to-use platform that was able to adjust to the needs we had at Dotdash. It was able to support the simple campaigns where we would send static creative to all recipients and the complex dynamic campaigns where we were customizing content. The scale and flexibility really made it a great platform for us to use.

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 has helped us build a welcome series that's much more effective than anything we had before.
  • It's much easier to analyze transactional campaigns than our previous ESP.
  • We're better able to run A/B tests and learn from the results -- all of which improves our email strategy.
