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.
MessageGears is a hybrid email marketing system that combines the security of an on-premises system with the scalability of the cloud. The service connects directly to any local or remote database, data warehouse, e-commerce system, or content management system. There is no need to extract, transform, or load customer data into the system or to move or replicate data. Features include subject line previews and testing, spam testing, and automation, drip and trigger campaigns.
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.
Your next major concern will be compatibility. It's not a shock that most businesses run on Microsoft Windows and use some form of Microsoft Office. Being able to use common third-party clients such as Microsoft Outlook can often be a concern, and even today, compatibility with Microsoft Outlook isn't necessarily guaranteed. This is especially true when sending and receiving meeting invites. It only takes one garbled meeting invite to realize how frustrating this can be in the real world. Even if using Microsoft Outlook isn't a concern, portability is. If the service is entirely web-based, then is there a means for me to take my email offline and send email when I connect?

Yahoo Mail takes extra steps to keep your account secure by automatically enabling spam filters and directing messages into the spam folder. It also recognizes some junk mail and will place these items in the trash bin rather than your primary inbox. Another positive feature our testers liked is the sender block, which lets you add an email address to a black list. Rather than redirecting emails from these senders into the spam or trash folders as other email services do, Yahoo Mail blocks these messages entirely.


ProtonMail is a basic email service that is easy to set up because it doesn’t ask for any personal information. You just pick a user name and password, and you’re set. Be aware that some features – such as mail collection and the ability to sync across multiple devices – are only available with its paid email service. But the free version does have email encryption, which is important if you send messages with sensitive information you want to protect. ProtonMail automatically unencrypts the message when it reaches the recipient’s inbox and is opened.


Effective email marketing campaigns are designed for all devices on which users can read their emails -- desktop, tablet, and smartphone. Email campaigns that are designed for mobile devices are especially important -- a quality known as "responsive design." In fact, 73% of companies today prioritize mobile device optimization when creating email marketing campaigns.
We tried to give as much value as possible in these emails without being spammy or annoying. We also tried to keep in mind that all of this influencer outreach was not only about the short-term benefit of acquiring links, but it also served the purpose to stake out a place in the customer success space and build relationships with important, smart people.

Your goals and objectives need to be different for whether it's an eblast (promotional email) or regular enewsletter. Eblasts are great for getting quick leads/sales, while enewsletters are better for staying top of mind, educating customers on new offerings, or providing helpful industry updates. I have found them to be very successful, but what works and what doesn't requires testing (of both the subject line and creative) and varies per business. Best practices for both types include have...
A: While email marketing isn't necessary for every business, it is a good way to reach customers and improve your overall marketing strategy. Email is a solid marketing platform, as most professionals and potential customers use email regularly. Your business doesn't necessarily need email marketing, but it's a good way to reach customers digitally.

Running in-house email servers does provide more control and wider customization as well as tracking and compliance for small to midsize businesses (SMB). But they require specialized on-site IT staff as well as the need to manually manage and support both hardware and software. A third-party hosted email service matches many of the advantages of in-house email without the expensive initial investment. The ability to manage the number of users, access the latest security protocols, and enjoy ease of connectivity and deployment of hosted solutions makes it a viable and competitive option.

We narrowed the 16 free email services to eight that we believe are the best options. We eliminated services that allow you to send free email messages but won’t let you receive messages without purchasing the service. We also discounted services that currently have free email accounts available but are either no longer offering support or have plans to discontinue them. We didn’t feel comfortable recommending a service that may not be around long term.

Analytics and reporting: Once you send an email, you'll want to determine how it's doing. Most services provide a range of data, including how many emails you sent, how many of them landed in inboxes, the bounce rate, who opened your emails, and the number of clicks and opens by location. Click-through rate and open rate are two basic metrics all email marketing services should provide. Those are important metrics to track for businesses.

On a more basic level, AI improves email marketing mechanics such as A/B testing and smarter audience segmentation. This can have immediate benefits in terms of optimizing your marketing strategies for different customers and sending the right content to the right people. On a more advanced note, AI can actually optimize email content for specific audiences and product campaigns.

Strong stuff, which means determining exactly how a potential email marketing service has implemented AI should be a key criteria for most marketers before purchasing.
Well, charity: water took an alternate route. Once someone donates to a charity: water project, her money takes a long journey.

With the project timeline and accompanying table, you don't even really need to read the email -- you know immediately where you are in the whole process so you can move onto other things in your inbox.
