The "From" address will be list-specific and can be set at the "List Settings" page of your list. To access the from address or add a new from address, first hover over the "List Options" tab and click "List Settings."
Under your "Basic Settings," click the "From Address" drop-down.
Then, click "Add New Email."
Once you do that, a box will pop over the page for you to add the email address. Type in the email address you want to use and click "Send Verification."
And that's it! A verification message will be sent to your email address. You must click that link in order to finish the verification process and start using your from address.
Use Something Subscribers Recognize
Along with its subject line, your reply address is the first thing your subscribers see of your email messages, so your reply address should be something that your subscribers recognize from wherever they signed up.
For instance, if they did at your website whose address is www.example.com, an address from example.com should be used.
If you are unsure of how to set up such an email address, contact the company that provides you web hosting service for options that are more than likely free or affordable.
Consistency and recognition are very important parts of an email campaign. If they don't recognize the address and name, they will be much less likely to open the message.
Use A Valid Address You Check Regularly
Your subscribers value the personal voice you use in email messages. By using an address you check regularly and encourage feedback or questions, you enhance this benefit.
And because some subscribers will send a message asking to be removed from your campaign, using a valid address is also required by federal law.
We Recommend NOT Using Free Addresses
Due to security setting changes at free email address providers, we recommend not using free email addresses from Yahoo, AOL, and other providers as your "From" address. We strongly recommend you do not use any free email addresses for your "From" address at all. Learn some tips on what email to use as your FROM email address in campaigns.
