How to write a Mars email address
- Start with the person's first and last name as they write it on LinkedIn.
- Apply
{first}.{last}@effem.com: Jane Doe becomesjane.doe@effem.com. - Use @effem.com, not the website domain (mars.com).
- 13% of addresses didn't follow a name rule (nicknames, added numbers or older aliases), so a guess can be wrong.
- Verify the address before you send, so a wrong guess doesn't bounce and hurt your sender reputation.
