Elastic Email as a secure and cost-effective email delivery engine

WHMCS Services sends mainly transactional emails, such as account creation, invoices, daily transactional data reports to business managers, password resets, system alerts, and the occasional client-specific notifications. As Andy, the WHMCS Services Director of Business Development, says, at first, he tried to send emails directly from his servers, but they always ended up in the spam folder. That was the moment when he decided he needed an email platform.

At that moment, he started to search online for an email service provider. Among other solutions, he discovered Elastic Email. The platform proved to be cost-effective and offered a referral program. These reasons convinced Andy to choose Elastic Email, and he’s been using the platform ever since. The referral program was particularly useful for WHMCS Services as they built a module with Elastic Email, allowing their customers to connect their WHMCS website with the Elastic Email API to send emails. Using the Elastic Email referral program, Andy earns money by sharing the affiliate link. Each time his customers start using Elastic Email to send their emails, he receives 20% of all their purchases for up to six months.

When I was using my service email I noticed people complaining: I'm not getting the emails. I'm not getting this. Then that's ok, you know what? Forget about this. Let's just try to find an email provider. And I found you. - Andy, the WHMCS Services Director of Business Development

Main Elastic Email features used by WHMCS Services

When we asked Andy what Elastic Email features he uses mostly, he replied that, apart from the referral program, he uses email logs to look at the email activity. He checks whether all emails were sent and delivered, or maybe there’s an issue he needs to address.

WHMCS Services’ success story - conclusion

Like thousands of other brands, WHMCS Services uses the Elastic Email API product to send its transactional emails. They do it with ease and successfully, without having to worry about whether their essential communication hit the recipients’ inboxes. WHMCS Services took it to the next level by creating a WHMCS module with Elastic Email and by using the referral program to earn money thanks to recommending Elastic Email to its customers.
