As mentioned in the tutorial on Email Settings with Siteground, Neltek recommends using Google's GMAIL with your domain email.
Indeed we personally use email in the way we describe below.
GMAIL (www.gmail.com) is an email system provided by Google that is free to use. It works very well indeed and has many features that are very useful.
Along with your GMAIL account you get other Google services e.g. calendar, 'drive' - Google's online office document provision (documents, spreadsheets, presentations etc.) and many more.
GMAIL is accessed via a web interface allowing the user access to their account from anywhere that has an internet connection. It also has apps that work on all major smartphones and tablets (including Android and Apple).
This way, any email stored with GMAIL is accessible via any device you own.
Also you can access GMAIL from a PC email client e.g. Outlook.
Step 1 - Create GMAIL account
Go to www.gmail.com and sign up for a new email account.
Log in to GMAIL and on top right you will see a 'cog' shaped icon. This is where you can change the settings.
Click on the icon as you can see in the picture above.
Select "Settings" from the drop down list.
You will now be presented with the settings screen. Select "Accounts" from the TABS at the top as in the diagram above.
Half way down you will see a section for "Check email from other accounts (using POP3):"
We will now add another account - select "Add a POP3 mail account you own".
Then Click on the button "Next Step >>".
You will then see the above screen.
Change the username to be the email address you are adding (this is the username for Siteground hosting that we use).
Do NOT check the "Leave a copy of the retrieved message on the server".
TICK "Always use a secure connection (SSL) when retrieving mail".
Optionally: "TICK Label incoming messages: ". This will put a label on the emails fetched from this email account so you can identify them. You don't need to do this but it may help. Gmail uses labels to sort emails.
The last option "Archive incoming messages (Skip the Inbox)" means the messages retrieved for this email address won't show in your inbox. They can still be searched for. Also if you have labelled them, then clicking on the label will show them. Again this is optional. Personally I leave this unchecked.
The final screen lets you set up the facility to send emails from this account.
Once approved - in the main Settings screen you will see a section for "Send mail as:"
Here you will see your gmail email address and the approved pop3 email addresses.
On the right you can select which Gmail uses as the default address to send from.
