Best Practices for Email Marketing. Tips to ensure that your email marketing messages are delivered to the recipient's inbox and not marked as spam.

Email marketing is one of the most cost-effective ways to reach your target audience, but it can be a frustrating experience when your emails end up in the spam folder. When emailing your customers or users about your referral program, you want to make sure your emails arrive in their inbox and get their attention. 

Spam filters have become increasingly sophisticated over the years, which means that even legitimate emails can be flagged as spam.

In this guide, we'll explore some best practices for avoiding the spam folder and ensuring that your emails are delivered to your users inboxes. Whether you're sending an email to prompt people to refer, or sending an email to welcome your new referred users, please make sure you consider the tips below. 

Here are some tips to help you avoid emails going to spam:


Optimize Your Sender Information: Ensure that your sender information is complete, updated, and accurate. Use a professional email address that's recognizable by your recipients. Go to your /settings tab in Referral Factory to do this.

Connect Your Own Mail Server: If you'd like to be in 100% control of your deliverability, then we advise connecting your own mail server to Referral Factory. Please make SURE that your email server does not have rate limits, otherwise you'll think your emails are sending when they are not. Go to your /settings tab in Referral Factory to do this.

Avoid Using Spam Trigger Words: Certain words and phrases are known to trigger spam filters. Examples include "free", "cash", "$", and "opportunity". Avoid using these words in your subject line or body text.

Avoid Large Images Files (or any image files if possible): the less bulky files your email holds, the more likely it will be to make it through the spam filters. 

Keep Your Email Length Appropriate: Ensure that your emails are concise and straight to the point. Long emails are a turn-off for readers, while short emails can be incomplete.

Test Your Emails: Test your emails before sending them to ensure that they look professional, are easy to read, and can be viewed on various devices and platforms.

Include a Clear Call to Action (CTA): Your emails should have a clear and concise call to action. Use action-oriented words such as "Share," "Refer," or "Copy" to make your CTA stand out.

Keep Your Emails Clean: Avoid using too many colors, fonts, or graphics as they can distract your readers from the email's purpose. A simple design with an easy-to-read font ensures that your email is clear and professional.

Ask Recipients to Add You to Their Address Book: Encourage recipients to add your email address to their address book or whitelist.

By following these best practices, you can avoid emails going to spam and ensure that your emails are delivered to the right mailbox and opened by your intended recipient.
