There are some suggestions for encouraging contacts to forward your email:
1. The more relevant and targeted the content, the more engaged and motivated the recipient will be to share it with their friends or colleagues.
2. A/B test different calls to action, for example, "Forward to a friend" or "Share with your Network". Better yet, name the target audience you want, for example, "Share with other Email Marketers".
3. Single subject emails are much easier to share. This eliminates the need for the sender to explain what caught their attention in the first place.
4. Remove the noise. Emails with visual and message clarity and simplicity are easier to forward.
