We narrowed down our list by eliminating vendors that don't specialize in email marketing campaigns or that don't work with small businesses. Next, we researched each provider by investigating its services. We considered pricing when available. After narrowing the list down to seven, we contacted each company's customer service department and posed as small business owners.

Email marketing solutions run the gamut from basic text-based email editors to fully designed HTML or JavaScript templates. Leveraging email for marketing can take several forms, so some packages will attempt to address all of them while others will seek to specialize. For example, some businesses might decide their most effective marketing tactic is a value-add newsletter delivered to a gated community of subscribers. Others might want to tie their emails directly to their product and sales engines, providing special offers and deals to recipients.

As an avid reader of [insert their site name], I love reading anything you write about, such as [insert article on their website], and anything you link out to. Sadly, I couldn’t find the article you were trying to link to, but I did happen to find another good webpage on the same topic: [insert url to webpage that you are building links to]. You should check it out, and if you like it, you probably want to switch the links.
Examples of this include things such as instant messaging (IM) and team chat tools, video conferencing software, online meeting collaboration tools, shared team intranet sites, and more. Some even integrate with third-party tools such as Slack, a highly popular collaboration tool that combines customizable chat "channels" with file sharing and project management. For those who want to integrate with certain apps more deeply or integrate with custom-developed apps they have built in-house, many bigger-name email services will provide robust application programming interfaces (APIs) that will let your in-house developers or consultants deliver on those needs. They will need to be involved in the email service selection process, however, as this is an important consideration during your evaluation period.
Post initial setup, a primary concern will be the log-on issue. If your organization is fine with a separate log-on for your email provider, then this step will be quick. However, that's not typically what businesses want or users expect. In general, users expect to sign onto their desktops and have their email and file sharing sign-ons happen as part of that one-step process. Not surprisingly, this is called Single Sign-On (SSO) and it's enabled in one of three ways: through the use of a back-end directory service like Microsoft Active Directory (AD); an identity management service, like Okta (one of our Editors' Choice winners in that category); or several compatible web services that include SSO along with other apps and email services, like Google G Suite Business and Microsoft Office 365 Business Premium (two of the top providers reviewed here). Which method you choose depends on how your business is configured today and your long-term cloud services strategy. It's definitely a conversation you'll need to have either with your in-house IT staff or your outside IT consultant.
Marketing emails need to be personalized to the reader and filled with interesting graphics. Few people want to read emails that are addressed "Dear Sir/Madam" -- as opposed to their first or last name -- and even fewer people want to read an email that simply gives them a wall of text. Visuals help your recipients quickly understand what the point of the email is.
Obviously, it takes more work to create and place guest posts, but it’s worth it if the publication is aligned and authoritative. We found a way to create additional value with this as well by working with internal HubSpot experts who wanted to get their thoughts out on a given subject. For example, here’s a guest post that Blake Toder wrote for the Usabilla blog:

Email marketing is an easy way to communicate directly with your customers who are interested in your business. You can also use email marketing to send personalized emails with the help of segmentation. With about 70% of businesses using email marketing, it's critical to invest in this technology, or you'll fall behind the competition. Businesses use this software to send emails about company updates, promotional emails, newsletters, event invitations and to gather customer feedback. 
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.
First of all, BuzzFeed has awesome subject lines and preview text. They are always short and punchy -- which fits in perfectly with the rest of BuzzFeed's content. I especially love how the preview text will accompany the subject line. For example, if the subject line is a question, the preview text is the answer. Or if the subject line is a command (like the one below), the preview text seems like the next logical thought right after it:

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.
