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.

Twilio SendGrid Email API

SendGrid Email API, I feel, is well suited for tech companies with smaller teams. I feel as if with a larger team of programmers, designers, etc. you may have better results with a competitor and coding things yourself. But for fast moving startups with quick implementation, nothing beats Twilio + SendGrid in those regards.

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

Twilio SendGrid Email API

  • Actually viewing previous emails dispatched. SendGrid does not have this feature - although it provides numbers on emails dispatched within 3 days for the cheapest plan.
  • The service asks you to pay more (although a minimal amount) to have visibility on email activity upto 30 days in the past.
  • The API doesn't allow an export of a report of email activity over a period of time. It can be quite frustrating at times to be limited in this way.
  • Their customer support isn't the best. Certainly some room for improvement there.

Based on 6 answers
Twilio SendGrid Email API is everything we want it to be, and we have no reason to look for any other solution. Features and pricing match exactly what we need. As developers for SaaS products, Twilio SendGrid Email API provides a great service. I hope that they stay this way and don't inflate the service with too many marketing oriented features, because there are other tools for that and Twilio SendGrid Email API is a API for sending email first and foremost.

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.

Twilio SendGrid Email API

We prefer Twilio SendGrid as a solution, simpler installation, very low failure rate (less than 1%) Our goal is a 1 step solution that we never have to go back to, that way the client is only billed once and their ROI remains high.

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

Twilio SendGrid Email API

  • The ability to get messages to our customers automatically at the right time allowing us to convert more often.
  • Streamlined processes so we're saving time every week.
  • Allowed the team to be very powerful and agile, we can get more done then we could before as we have more time to focus on other core functions.
