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.
We spent 120 hours testing 16 free email services, narrowing our list to the eight services we believe are the best options. These services have sufficient inbox storage and tools to make it easy to send, receive and store messages. Gmail is our top pick because it’s the easiest to use and comes with the most services, including access to Google Calendar, an attachment preview, automatic spam filters and direct import of social media contacts into its address book.
MailUp gives businesses the tools to send newsletters, promotional emails and transactional emails from one platform. The MailUp email and SMS delivery platform combines email marketing tools with SMTP relay for transactional emails and plugins for e-commerce, CRM and CMS systems. The service's pay-per-speed pricing is designed for midsized companies looking to scale their email marketing efforts.
