Normally all email software is capable of customizing the name that appears in the FROM line of your email marketing message.
So, instead of “From:firstname.lastname@example.org” you can send an email that says “From: email@example.com“.
This approach is more friendly, inviting, and more likely to get opened and read. Think about it. How often do you delete messages from such unfamiliar and suspicious sources as: “From: firstname.lastname@example.org” ?
Also, email marketing campaigns with generic email addresses in the FROM line are more likely to be blocked by spam filters. Your email could be labelled as spam, based on the generic nature of the FROM field.
Always use a personal or “human” FROM field to enhance the success of your email marketing campaigns and decrease the risk of being perceived as spam.
