Evopos can send emails by using your email providers server.

Evopos simply acts as a client and so any issues around emailing are down to your email settings and provider.


  1. Navigate to Settings\System\Comms
  2. Enter your outgoing / SMTP server details, username and password
  3. Click Save

Sending Email

Emails can be sent from multiple areas in Evopos.

  • Email button in Contacts
  • Email button in Report Viewer
  • Tick Box in Sales Finish
  • Bulk Emailing in Contacts\Comms

Email Limits

Email providers can limit the amount of emails you can send per day.

  • Google Gmail - 100 per day
  • Microsoft Outlook/Hotmail - 300 per day

Bulk Email Provider

We recommend SendGrid for users wishing to send large amounts of emails.

Reply Email

You can set a reply email if your provider does not support sending from multiple addresses under one account.

In your operator email from field, enter reply: then the email address. eg: reply:example@email.com

When receipt receives the email it will be from the main email address set in System\Comms, but when they reply it will use the reply email address.


Evopos acts as a simple SMTP email client, most error messages you receive will be from the email server.
  • Check your SMTP details and credentials are correct
  • Check you have internet access
  • Read the error message, in can provide details on why the email did not send
  • Email providers set email limits on how many you can send per day
