Customer.io is an email marketing tool that can be used by various different roles within your business including marketers, product managers and of course, growth hackers. Users can send targeted emails to your visitors on your website or to mobile app users depending on their activity. You are notified when they have read your email and/or if they click on one of the links. It also includes A/B Testing capabilities.
I think this email also makes quite a brilliant use of responsive design. The colors are bright, and it's not too hard to scroll and click -- notice the CTAs are large enough for me to hit with my thumbs. Also, the mobile email actually has features that make sense for recipients who are on their mobile device. Check out the CTA at the bottom of the email, for example: The "Open Stitcher Radio" button prompts the app to open on your phone.
As a growing business, you may also be looking for a CRM solution, and you'll find that the more advanced email marketing services have begun to crossover into CRM. It makes sense: Both types of software deal with managing and communicating with customers. A handful of these services are one-stop shops, either offering both email marketing and CRM out of the box or as add-on services.

Discussion lists often require every message to be approved by a moderator before being sent to the rest of the subscribers (moderated lists), although higher-traffic lists typically only moderate messages from new subscribers. Companies sending out promotional newsletters have the option of working with whitelist mail distributors, which agree to standards and high fines from ISPs should any of the opt-in subscribers complain. In exchange for their compliance and agreement to prohibitive fines, the emails sent by whitelisted companies are not blocked by spam filters, which often can reroute these legitimate, non-spam emails.[11]
If you want to code your own emails, you have the freedom to do so. But this is an advanced skill that requires a good bit of technical know-how. Here’s what you need to take the coding leap—whether you’re just getting started, wondering about the basics of HTML emails, or looking for a guide to coding them. We’ve also rounded up a few more resources you might need as you become a certifiable email pro. If you're considering another platform, check out our comparison guide before you make any decisions.
Great companies are always evolving, and your customers expect to experience change. What they don't expect (because too many companies haven't lived up to this end of the bargain) is to be told about those changes. That said, this email from ModCloth serves as a refreshing change of pace. If you're going to change the way you communicate with a lead or customer, give them clear, fair warning so, if they aren't on board, they can make the necessary adjustments to keep their inbox clean.

A web-based interface is often available to allow people to subscribe, unsubscribe, and change their preferences. However, mailing list servers existed long before the World Wide Web,[1] so most also accept commands over email to a special email address. This allows subscribers (or those who want to be subscribers) to perform such tasks as subscribing and unsubscribing, temporarily halting the sending of messages to them, or changing available preferences - all via email. The common format for sending these commands is to send an email that contains simply the command followed by the name of the electronic mailing list the command pertains to. Examples: subscribe anylist or subscribe anylist John Doe.


A safe email testing tool for staging and development, Mailtrap enables you to inspect and debug your email samples before delivering them to your customers. It helps you keep your email messages clear of spam filters and test HTML elements for compatibility with popular email clients. The Mailtrap blog also offers helpful information such as reviews of email deliverability testing tools.

With Vero, users can track and store customer data and events in real-time. Using this information, you can create segments without having to do any coding and send out automated emails. For example, users who have just abandoned the shopping cart can be targeted with an email just hours or days later. In terms of deployment, Vero can be integrated with an email delivery provider, such as Sendgrid.
Not only is InVision's newsletter a great mix of content, but I also love the nice balance between images and text, making it really easy to read and mobile-friendly -- which is especially important, because its newsletters are so long. (Below is just an excerpt, but you can read through the full email here.) We like the clever copy on the call-to-action (CTA) buttons, too.
In our email marketing software review roundup, we test the top email marketing tools available based on how easy it is to create emails, build subscriber lists, set autoresponders, and pull in other communication-based tools, such as social media management, and web analytics software. To that end, we selected Campaigner and Mailchimp as the best pure-play email marketing services. If you need a more complex tool that can build comprehensive workflows designed to automate the email marketing process, then we recommend HubSpot and Salesforce Pardot, which are better served as marketing automation tools.

Electronic mailing list servers may be set to forward messages to subscribers of a particular mailing list either individually as they are received by the list server, or in digest form in which all messages received on a particular day by the list server are combined into one email that is sent once per day to subscribers. Some mailing lists allow individual subscribers to decide how they prefer to receive messages from the list server (individual or digest).[2]
Electronic mailing lists usually are fully or partially automated through the use of special mailing list software and a reflector address set up on a server capable of receiving email. Incoming messages sent to the reflector address are processed by the software, and, depending on their content, are acted upon internally (in the case of messages containing commands directed at the software itself) or are distributed to all email addresses subscribed to the mailing list.

But if people don’t believe those reasons, they don’t buy either. As long as you seem like a friend who’s trying to help them, people are likely to believe that you’re sincere and that buying from you is a good decision. That’s one of the main reasons email marketing can work so well; it’s relatively easy to come off as a friend. Especially the other two email marketing strategies are good for making people see your good intentions. That said, if your offers don’t make people think you’re genuinely trying to help them, something is wrong.
Emails triggered by milestones, like anniversaries and birthdays, are fun to get -- who doesn't like to celebrate a special occasion? The beauty of anniversary emails, in particular, is that they don't require subscribers to input any extra data, and they can work for a variety of senders. Plus, the timeframe can be modified based on the business model.
Mailing lists have first been scholarly mailing lists.[3] The genealogy of mailing lists as a communication tool between scientists can be traced back to the times of the fledgling Arpanet. The aim of the computer scientists involved in this project was to develop protocols for the communication between computers. In so doing, they have also built the first tools of human computer-mediated communication. Broadly speaking, the scholarly mailing lists can even be seen as the modern version of the salons of the Enlightenment ages, designed by scholars for scholars.[4]
Sample review: “See what happens to your emails after you press send…you’ll know exactly when they opened your email and whether or not they clicked on your link. BananaTag will even tell you whether they’re on their desktop or mobile device. And best of all, your email appears NO different to your contacts. All of the tracking is done seamlessly without any change in the user experience.” — BuzzBlogger
Wow such a detailed review! I have tried MailChimp before and I found it too expensive. After that i’ve signed up to Mailerlite and got hooked. It’s either free or cheapish depending on your subscribers’ lists. With other email software providers, you’d need to make an investment even if you’re running a small shop or a blog. And let’s be honest, not everyone of us can afford it :)
For example, I can safely share that I listen to a lot of music, and I’m almost fanatic about sound quality. I might listen to an album with poor sound quality once, but I probably won’t go back to it. And to be clear, 95%+ of new recorded music has what I consider poor sound quality (due to an absurd standard of perceived loudness, which takes away natural dynamic range from the sound). That said, I’m not a hi-fidelity sound geek. I’m perfectly happy with my high-end studio monitors—I don’t buy $1,000 power cables, $5,000 CD-players, or $20,000 loudspeakers capable of playing back sounds too high for dogs to hear.


Thanks for the article, it was also interesting and inspiring to see your other ventures in diverse fields. Would like to connect 1:1 in the near future. Meanwhile, even I had done a similar comparison as I myself handle email marketing for my organization. Do check it out as well as for the readers of the blog since it covers 2 additional players.
Activation: A new user creates an account but, they do not use your product within the first 7 days. Create an  “activation” campaign that sends an automated email with their login information, steps on how they can get started and include a video demonstration for additional support. You can also invite them to a one-on-one meeting to walk them through the product and answer any questions they may have.
