Yes, however, we do not recommend using images in your campaigns since the main purpose of most cold email outreach and follow-ups is to look like they are 100% manually written. When you send out regular email correspondence, you don't usually insert images. You just email your client with a human message.
That's how Reply works. It’s designed to send short, sweet and straight-to-the-point messages, which look like you actually went and typed them manually.
If you still need an image to be added, please contact [email protected] or Live Chat support agents and we’ll enable this option for you.
P.S. Try to avoid using an image with spaces in the name. Some email clients make auto-replacing "-" to "+". And it can break the link.
