When you setup the DNS section of your account to run Glow from your own domain name, in Step 4 you choose an email address that will be shown to your clients when they receive email notifications from your account. You do not need to create a mailbox for this purpose. Glow will handle email and to your clients it’ll just look like you’ve sent the email (ie. it’ll show the email address you chose in the setup process above).
However, you may also be using this same email address as the one that your clients use in order to create support tickets, eg. support@, help@ etc. In this case, you do need a standalone mailbox.
If you decide in the future that you no longer want/need this mailbox (and therefore that you no longer want to use Glow’s ticket system), you may wonder if you can safely delete the mailbox from your email provider, without it impacting Glow.
The answer is that you can go ahead and safely delete the mailbox, providing you are definitely no longer going to use the ticket system. If you’re still intending to use the ticket system and you delete the mailbox, then your clients will no longer be able to raise tickets to you from email, they’ll need to raise them from the dashboard.
All other email notifications from Glow will continue to work as normal because they do not require you to have a mailbox setup.
