Sender name

1. Your name is the first thing your email recipient notices, so choose an easily recognizable name. For example, if your company name is Zylker and your name is Tom, then Tom | Zylker.com is easily recognizable.
   

1. Avoid punctuation marks in your name. Spam filters and contacts will avoid emails that contain too many punctuation marks.
   Eg: P@_t_r_i_c_i^a will look strange and malignant. Whereas Patricia looks genuine. 

1. Use spell check. Even a small typo can lead to contact loss.
   

1. Use the same sender name for every email.
   

1. Avoid using an email address as your sender name. This is a common spam tactic and you'll likely find your email in the spam folder.
   Example: For a sender named Jim, it is better to use Jim than jim@zylker.com.

Sender email address

1. Select an email address from your organization's domain or sub-domain. Example: patricia@zylker.com or patricia@admin.zylker.com. 

1. Avoid using sender addresses from free ESPs such as Gmail, Yahoo!, and AOL. 

1. Your sender address should make it clear that your recipients can respond to your message. If you send from something like "no-reply@yourdomain.com", your emails are more likely to land in the spam folder. 

1. If you have a new domain, you should build your domain reputation gradually through contact segmentation (targeted marketing), tackling bounces, and avoiding role addresses, complaints, and unsubscribes. Learn more about how to improve your domain's reputation.

1. If you want to use a secondary domain, make sure you include this information in your email footers:
   "We are sending you this newsletter because you have subscribed/signed up with us at yourdomain.com" 

Templates

Note: Make sure that the Image:Text ratio is not greater than 40:60.

Email Subject

1. Your subject line should be crisp and easy to understand. Address your recipients by name instead of their email address. Use the $[FNAME]$ and $[LNAME]$ merge tags to include their first and last name in the subject line.
   
2. Personal information should not be included in a subject line.

Images

1. The Image:Text ratio in your email content should not exceed 40:60. 

1. Avoid content with a single image. By default, images will not appear when contacts open an email. Contacts will have to choose to display your image if they are going to see it, so if your email content appears as a single image, it will display as a blank message to your recipient.

1. Use appropriate image resolution. Too low and your image will be hard to see; too high and your image will take a long time to load.
