As spam filters get more and more aggressive, it is harder, even for legitimate senders, to ensure that your emails get delivered to your recipients. This article will cover some easy-to-implement tips that increase your chances of reaching your audience.
URL shortening services such as Bitly and TinyURL are great for use on the web, but you shouldn't use them in your emails. Many services, including popular providers such as Gmail, behave more aggressively to emails that include shortened URLs. As an alternative, you can:

You might be tempted to send out image-only emails, since this is an easy way to ensure that all recipients, regardless of which email provider they use, sees your message the way you designed it. However, spam filters still have difficulty parsing images. This, combined with the fact that spammers frequently hide their messages using images, means that your email will most likely end up in spam folders.
Despite the increased amount of time required to craft HTML-base emails, these should be the standard you use. Use images in your emails only where necessary.

By including your contact details, you can also avoid false complaints about you being a spammer--users can contact you directly for clarification or if they have any questions.
As we've mentioned above, recipient engagement is important, so make it easy and possible for your users to get in touch with you. Avoid using [email protected] or other similar email addresses that discourage your users from responding to your emails.
