Emails with a dodgy subject line or from an unknown source can appear to be spam. Customers frequently delete these emails since they appear to be off. An emoji may elicit a positive response from some clients. Others may be prompted to look for the unsubscribe link if they receive the same subject line. You must personalise your material to meet the needs of your audience. Knowing your readers' interests and demands ensures that your message reaches the inbox rather than the spam folder. Customers will know which emails they're signing up for and how often they'll be receiving emails from you if you create a permission-based email list with a check box for them to opt-in to your mailing list.
