SMTP stands for Simple Mail Transfer Protocol, a configuration that helps you send or relay outgoing mail between the email senders and recipients.

Suppose you send emails to your vendors or clients directly on Deskera Books +; in that case, you must configure the SMTP beforehand so that your recipients are aware that the email is coming from you.

To configure SMTP, follow the steps below:

  1. Login to your Books+ account.
  2. Go to Setting on the sidebar menu.

3.  Select Emails.

4.  When setting up your SMTP, fill in the fields below:

  • Sender name - This can be your name
  • Sender email - Your email address
  • Username - You can use similar email address saved in the sender email box
  • Password - Your email's password
  • Server Host Name - Your email's host name
  • Server Port Number - This should be in numerical format
  • Server security - Tick the checkbox to allow SSL

5.  Once you have entered all the information above, click on the Test Connection button.

6.  Next, a pop-up will appear, asking you to send a test email for testing purposes. Click on the Send button after entering the recipient email.

7.  Your recipient should be able to view your email address in their inbox.
