How to Improve Email Deliverability

Ensuring high email deliverability is essential for maximizing the effectiveness of your email campaigns. When using mySMTP, implementing the right strategies can help ensure your emails reach inboxes instead of spam folders. Here are key strategies to improve your email deliverability:

1. Authenticate Your Emails

Proper authentication helps prevent your emails from being marked as spam. Implement the following authentication methods when using mySMTP:

• SPF (Sender Policy Framework): Authorize mySMTP’s mail servers to send emails on your behalf.
• DKIM (DomainKeys Identified Mail): Digitally sign your emails using mySMTP's record to verify authenticity and build trust with ISPs.
• DMARC (Domain-based Message Authentication, Reporting, and Conformance): Set policies for handling unauthorized emails and monitor reports via mySMTP's DMARC monitoring features.

2. Use a Dedicated IP Address

If you send a high volume of emails, consider using a dedicated IP address through mySMTP to maintain a strong sender reputation. This prevents your email reputation from being affected by other senders sharing an IP.

3. Warm Up Your IP

Gradually increase your sending volume over time to build a positive reputation with ISPs. mySMTP provides guidance on IP warm-up strategies and recommended sending limits.

4. Maintain a Clean Email List

Regularly clean your email list to remove inactive, invalid, or non-engaging recipients. mySMTP offers email verification tools to help ensure your list remains clean and effective. Use double opt-in features provided by mySMTP's MailWizz to confirm subscriber intent.

5. Monitor Blacklists and Reputation

Check your sending domain and IP against blacklists (e.g., Spamhaus, Barracuda) using mySMTP’s monitoring tools. Additionally, track your sender reputation with Google Postmaster Tools and mySMTP analytics.

6. Optimize Email Content

• Avoid spam-triggering words (e.g., "free money," "guarantee").
• Use a proper text-to-image ratio to enhance readability.
• Ensure emails are mobile-friendly and properly formatted to comply with mySMTP’s recommended best practices.

7. Set Up Feedback Loops (FBLs)

Register for feedback loops with major ISPs through mySMTP’s FBL integration to monitor complaints. Remove recipients who mark your emails as spam to maintain a positive sender reputation.

8. Monitor Bounce Rates with mySMTP Analytics

High bounce rates can harm your sender reputation. mySMTP helps classify and handle bounces appropriately:

• Hard Bounces: Remove permanently undeliverable addresses.
• Soft Bounces: Retry sending later, but use mySMTP’s analytics to identify and remove addresses that repeatedly bounce.

By implementing these best practices with mySMTP, you can enhance your email deliverability, ensuring that your messages reach inboxes effectively.
