Man, I’m… Oh my goodness…
You really CAN NOT afford $5 per mailbox for G-Suite? Or $3 per mailbox for Zoho Mail?
Okay, let’s set some things straight. First of all, you don’t need to configure ANYTHING at Cloudways to connect email services to your domain. They provide Elastic Email and these SMTP options for those who want to send transactional emails. Transacional emails are messages sent from your website to your users, such as a WE RECEIVED YOUR ORDER message from your ecommerce website.
VPS and dedicated servers usually aren’t configured to send those messages, because they can be easily abused. So it’s up to you to provide this, and that’s why Cloudways provides Elastic Email integration, or you can use another provider. But again, this is for transactional emails only. And remember, Cloudways is a hosting company, not an email service provider.
What you need is a mailbox service, that is, a service that can send and receive emails from and to your domain. You cannot use Mailgun, Elastic Email or whatever, for that purpose. And you will not configure this using Cloudways, nor you need them to.
If you sign up to G-Suite or Zoho Mail they’ll provide you with some instructions on how to configure your domain to send and receive emails. These instructions will then have to be applied to your DNS provider - that is usually the company where you purchased your domain, and not Cloudways. Most of these provide you with a panel where you can change your domain entries.
I understand that your employees currently use Gmail addresses. That is not a professional way to conduct business online, so you should seek to stop using these Gmail addresses and instead use email from your domain. If you’re already used to the Gmail interface, then you can sign up to use G-Suite to use their services with your domain - that is, you’ll be seeing Gmail, but it will be sending and receiving from your domain and not from @gmail.com.
I also understand that you may be doing this for a while and don’t want to lose contact with your current customers during this transition period. So, you can set up an autoresponder message on your old addresses so your customers can know where to reach you. And you can migrate your messages from your old address to your new address.
Unfortunately there is not a free way (or any way at all) to simply make your current Gmail accounts work on your domain.
If you’d like to set up something using Zoho or G-Suite, PM me and I will be glad to quote this for you.
