Locating your Power Diary From Email for Other eFax Services

A unique Power Diary 'sending' address is also used for each practice. This helps maximise email delivery and therefore your emails are less likely to be marked as Spam.

Normally this happens behind the scenes and there is no detectable impact for practices or email recipients. Third-party eFax systems, however, detect the difference because they are utilising the underlying sending email address to validate and match to your eFax account. To address this you need to add your unique sending email address to your eFax accounts list of accepted 'From' addresses;

    1. Identify your 'From' email address by sending yourself an email from your Power Diary account or contact us at
    2. When you get the email click to expand the sender information. You should see the email address and be able to copy it.

Hint 💡

It should look something like the below:

    3. Log in to your third-party faxing account and paste this email address to your permitted 'From' or 'Sending' addresses.

This email will be delivered to your e-faxing service, but the end recipient will only get the letter delivered as a fax message.
