MoonMail leverages Amazon’s cloud network to send their email and was built with volume in mind. Their free plan however is one of the most restrictive, with just 300 emails a month, and a daily cap of 1 campaign a day (with only 10 recipients per campaign). You’re obligated to use their own domain as the email sender address, and have no access to automations. Support and the ability to edit custom fields is also limited. Plus, we have to say their tool isn’t the easiest to use, with a lot of back and forth required to set up campaigns.

Customers can take advantage of professional (and mobile optimised) email templates, various customisation options, easy set up and engagement-driving action blocks. This software also includes list building tools, automated welcome emails, contact list segmentation, and email tracking.
If you offered subscribers a coupon in exchange for their email address, make sure you set up your email automation to actually send the coupon code in the email. Create an obvious CTA that takes users directly to your website to redeem the coupon. If you offered a PDF or something else in exchange for an email, make sure it’s included in the first one.

Another option, which is really more theoretical than anything else, is running your own email server. A quick cost/benefit analysis often makes this an unrealistic option for most small businesses. Sending out emails isn’t that much of a problem. However, if your email server doesn’t have a good sender reputation, your emails won’t be accepted by major email services such as Gmail, Yahoo, AOL etc.

As an email service that’s strongly geared to ecommerce, Omnisend has a lot of exceptional features, including automation workflows, the ability to automatically add your store’s products to your newsletters, and cool email add-ons like scratch cards and gift boxes. The bad news – none of these are available on the free plan. Regardless, the free plan is pretty hard to beat if you’re looking to send email in high volumes, with an allowance of 15,000 emails per month (2,000 per day). You also get A/B testing, website tracking, 24/7 support, deep reporting, and up to 3 forms/landing pages. Not bad at all.
