Amazon Simple Email Service (SES) vs. Customer.io

Amazon Simple Email Service comes with the bundle of Amazon Web Services (AWS) and it also offers a limited number of emails per month for free. One who has a technical background and wants to send custom emails with custom domains in a professional way can go with Amazon Simple Email Service. If you have no technical background or tech team, it might not be useful for you.

This tool is well-suited for companies looking to run email marketing campaigns or send out newsletters regularly to their users/customers. The workflow setup is especially useful for companies who want to send specific emails based on user behavior - i.e. they've not logged in recently, have bought a specific product, haven't opened any emails, etc. This could also be useful for freelancers like me since you can create different workspaces within Customer.io. I have configured it this way to handle email marketing for a few of my clients, and the software keeps everything organized and separate. This might not be the best tool for small businesses, considering the price. It may be better to start out with a cheaper email marketing tool, and then if/when necessary, scale-up with a tool like Customer.io.

• As compare to other vendors that I have integrated response is very quick.
• You can verify both domain or email to send out the emails from.
• While setup you can easily configure it with your domain with few clicks like adding CNAME, DKIM records
• Easy to use with or without access key and secret key within aws servers. You can directly map permissions to servers to go without credentials using boto3.

• Managing users, attributes and events. You are easily able to modify any user, based on their ID, and add or remove attributes, assign events to them. That makes it very easy to segment later and to assign them to several campaigns based on behavior. Just a warning: this integration isn't so easy (at least it wasn't for us).
• Creating workflows of campaigns is very easy. You can quickly create behavioral campaigns based on attributes, segments and add elements to the workflow. You can send an email, then wait, then send another, then exit the campaign if they converted, etc. The workflow is easy to configure and very powerful for automation.
• We don't use many email templates (we make them in MJML) but it's very easy to add senders, to change templates and in general to test designs.
• Deliverability works very well, at least for us. It sends emails pretty fast and without issues.
• Exporting is very quick and easy. Importing wasn't a feature until recently, but it works well too.
• Seeing activity it's also useful. In general, logs are awesome (be it of a customer, of activity on the site, email sends, etc.).
• We don't use environments, but it might be very useful for a bigger company.

• While the service limits are one of the main points that keep the delivery metrics so reliable, it can be stressful to get a new implementation out the door quickly.
• If you're looking for a point-and-click style email delivery tool, this is not the right type of product for you. Amazon Simple Email Service is for a developer-centric approach to implementation into existing applications, processes, and services.

• Customer.io needs to be more known! I don't know why they don't come up as a direct competitor to Iterable and Braze.
• Their new Design Studio drag + drop tool could be improved with further customization.
• Reports aren't the strongest - I use Amplitude to do all my Customer.io reporting.

Customer.io has drag-and-drop functionality for their campaigns that is very fun and intuitive to use. The audience build functionality strikes the right balance between usability and meticulousness. They also have an array of actions -- time delays, time windows, waitUntils -- that allow you to customize the timing of messages.

We did not have the need of contacting Amazon for support. The documentation they provide is of great quality. Examples are easy to follow. One thing to have into consideration is we didn't have the premium support for AWS, so I can't provide details on how good or bad this service is, but in general, the basic support I had was great.

Mailchimp has a fixed monthly price, and with the number of emails that we sent, it's pretty expensive. Since our mailings are quite infrequent, using Mailchimp didn't make financial sense for us, even though Mailchimp is a more polished, packaged solution for email marketing. We evaluated other email delivery solutions as well and didn't find anything that matches Amazon SES on reliability and pricing.

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.

• SES is still more cost effective than other email services like Mailgun.
• Unless we have a high-traffic month, staying within the free tier is very nice for our bottom line.
• Not having to spend time worrying about SES reliability saves us frustration and money.

• Positive impact on the sales side. I'm not sure about the specific ROI (you have to include the designer and the time it takes to set up) but you certainly get back the investment in a few months, once you are able to scale your email marketing.
• Customer experience is way better by having more segmented, contextual and accurate messages sent to them.
• Integration is costly and it will take several days or weeks to be fully achieved. Expect to invest some money on this.
