Data protection is another key email security concern. Inboxes often contain GBs of business-critical and personal data, so not just hackers but also legitimate marketing companies can make big money off mining email data—and this sometimes includes the very company that is providing the email service to you. Fortunately, most companies, including your hosting provider, are pretty good about keeping out of private data, but it's important to be aware of when these policies have failed. Security breaches are commonplace and it's important to know how your data is being managed. To protect yourself, be sure to inquire about data safety capabilities on the provider's side, especially around encryption and malware scanning. But be sure to implement additional measures on your side, as well, including encryption for those using local email clients as well as deploying personal virtual private networks (VPNs) to folks accessing their email from multiple locations.
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.
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.

The best email software providers offer user-friendly interfaces, making it easy for anyone to set a campaign and build appealing newsletters. Worried about HTML and graphic design skills? If you want to build your newsletter in HTML, you can certainly do that. However, it is best to choose a platform offering a wide range of templates and stock images you could potentially use, such as Active Campaign. Some of the best email software also offers tools that test your messages for spam. They will warn you if your text contains words that might trigger red flags from email providers. After all, you don’t want to see all your beautifully designed messages end up in your subscribers’ junk folders without an even remote chance of getting opened. The best email provider services will even block your address if they detect any spam suspicion.

Most companies will prefer a third-party solution since not only will these be more capable, they'll also be supported more effectively by related back-end apps, such as mobile device management (MDM) platforms and mobile-oriented endpoint protection solutions. You'll also have an easier time pushing a third-party platform out to registered client devices, though some hosted email providers can help with this step.
If you receive an email or call from someone claiming your computer is out of date, be very wary. If they further ask you for your personal information, Wi-Fi information or IP address, you’ll know for certain it’s a scam. They’re simply trying to steal your identity or hack your computer. If you’re uncertain, contact the actual company they claim to represent to see if there is anything wrong with your accounts.
