5. Avoid Spam Filters

The most obvious problem is when you send an email to the spam folder of a subscriber. You're already in control of sending emails and have chosen the right email marketing provider.

These are the top email marketing tips to prevent your emails from getting lost in spam folders:

• Provide an easy way for subscribers of your email to unsubscribe.
• Use a reliable IP address to send your email campaign. This is an IP address that you haven’t used in the past to send spam.
• Verify that all recipients have opted in to receive your emails.
• Keep your email template code clean.
• You can use verified domains to send emails
• Avoid using "salesy language" too often.
• Ask subscribers to whitelist their emails and to add you to their address book.
• Include your location.
• Do not "bait-and-switch," using deceptive subject lines.

You can do almost everything if you use a reliable email marketing service.(Aweber, MailerLite, GetResponse etc.)
