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

Twilio SendGrid Email Marketing is perfect for organizations both big and small that may be on a lower budget. It is a very affordable solution for users with a large number of email addresses. While other providers may offer "free" storage for email contacts... the cost to send campaigns to those contacts can be very costly. While they do not offer widgets or other integrations for websites/social media... it is very easy to import and manage contacts. Additionally, they offer a comprehensive self-help support section online, but it's also easy to hop on the phone or on chat with a rep if you ever need technical support or assistance. Twilio SendGrid Email Marketing may not be the most affordable solution for users who are not currently sending email campaigns to their users, but are simply storing email contacts

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.

Twilio SendGrid

  • Drag and drop email designer for transactional emails - super nice even though I do code, it's much quicker and easier to implement without code.
  • Very simple implementation. Only a few lines of code need to be added in our backend and boom we were up and running in less than a day.
  • Listening to customer feedback. They regularly send emails about new features and ask for feedback to improve their software.
  • Some of the cheapest and best dedicated IPs.
  • Easy integration and setup between marketing and transactional emails. Super helpful to have everything in one place.
Evan Laird | TrustRadius Reviewer

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

  • 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.

It has the potential to be really cool. However, it feels as if it was created by developers for developers (and I work with developers, yet even for me the instrument was somewhat not easy to use - just read SendGrid's help manuals...) However, if you are into data and your way of thinking is more mathematical rather than lyrical, you'll enjoy this instrument

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

With ExpressPigeon, SendGrid stacks up very well and actually provides just as much functionality for us as ExpressPigeon, but costs surrounding that use was advantageous with ExpressPigeon. SendGrid has recently added functionality that brings it closer to Act-On, specifically on the marketing automation end. This really allows users to create long-term campaigns.

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

  • Our clients experience significant ROI from their web forms - without receipt of forms, many of them would not still be in business.
  • As a solution for clients' sites, we find SendGrid is a fast installation and a 1 stop problem solver, saving us man-hours.
