Why are my emails appearing with different formatting when I send them?
This is usually a result of copy-pasting from an external source. When you copy-paste into Pipedrive's mail client, it will keep the formatting of the outside source in which you originally composed it, such as a word processor or other email client.
To get around this, you can use email template feature to compose templates for emails you send regularly. Alternatively, when you do need to copy-paste something, make sure to paste any text without formatting (CTRL-SHIFT-V on Windows, CMD-SHIFT-V on Mac).
