Email marketing is the practice of sending various types of content to a list of subscribers via email. This content can serve to generate website traffic, leads, or even product signups for a business. It's important that an email campaign's recipients have personally opted in to receive this content, and that each newsletter offers something of value to them.

For any business user or organization today, the decision to use email is a no-brainer. Business simply can't be done in many cases without it. But that doesn't mean you can interchange email platforms or service providers at will. Digging into the capabilities of these services reveals a great deal of additional feature scaffolding that surrounds almost every email implementation by necessity.


Email services typically charge between $2 and $10 per month for their paid services, depending on how much mail you need to send and receive. The biggest differences between free and paid email services is the size of the files you’re allowed to attach to outgoing mail, how many emails you can send per day, how much backup and inbox space you’re given, and the level of customer support you can access. Most free email services give you enough inbox and online backup space combined to hold hundreds of thousands of emails, but they typically limit the number of email messages you can send in a day to about 100. This is plenty for most people using an email account for personal use. But if you have a home business or know a lot of people you need to email every day, then it may be worth purchasing an email account with unlimited outbound messaging.
But your service provider isn't your only worry. If you've opted for any third-party email integration, like combining your email with a third-party customer relationship management (CRM) provider (such as Salesforce), that opens your company's email up to either data-snooping apps deployed by Salesforce or to any data breaches that originate with that service. So the more informed you can be about what's attached to your email service, how that data's being used and accessed and especially by whom, the better off you'll be when it comes time to send confidential email.
We learned that it takes a lot of steps to set up and verify an iCloud account and it isn’t easy. But the email program itself is impressive as it automatically saves contact information to your contact folder as messages are opened or sent. You can create alias email accounts and view them all in a single inbox and write automated reply messages for when you can’t return messages right away. We were really impressed with how fast our images and documents attached to outgoing messages using iCloud Mail, much faster than most services we tested. But you can’t preview these files once they’ve been attached.

ProtonMail was founded in 2013 by scientists who met at CERN and were drawn together by a shared vision of a more secure and private Internet. Since then, ProtonMail has evolved into a global effort to protect civil liberties and build a more secure Internet, with team members also hailing from Caltech, Harvard, ETH Zurich and many other research institutions.
“Third, tell me how it benefits me. I’m very very active in my charity work, but your startup is not a charity…”We thought you’d enjoy meeting young entrepreneurs” – bzzzzt. I DO enjoy meeting young entrepreneurs, I do it all the time as a matter of routine at conferences and through friends and so on. But if you’d like more than a friendly pat on the back and encouragement, then treat me like a businessperson – let’s find something that’s mutually agreeable. “If you could join us as an advisor, we’d be able to compensate you with stock options in a quantity appropriate to our stage of development.” – yay.”
We also love how consistent the design of Uber's emails is with its brand. Like its app, website, social media photos, and other parts of the visual branding, the emails are represented by bright colors and geometric patterns. All of its communications and marketing assets tell the brand's story -- and brand consistency is one tactic Uber's nailed in order to gain brand loyalty.
Pay attention to the amount of inbox storage available, because once you reach the cap, you’ll have to  start deleting messages in order to receive more. Many free email services offer a terabyte or even unlimited storage, which is helpful if you tend to receive messages with large attachments, like image and video files. However, even a few gigabytes of storage gives you enough space to hold between 100,000 and 300,000 messages.
When people talk about email marketing, lots of them forget to mention transactional emails. These are the automated emails you get in your inbox after taking a certain action on a website. This could be anything from filling out a form, to purchasing a product, to updating you on the progress of your order. Often, these are plain text emails that marketers set and forget.
