Best Practices for Email Deliverability

Maintaining high email deliverability is crucial for successful nurturing campaigns in VanillaSoft. This article provides best practices to ensure your emails reach their intended recipients while avoiding spam flags.

Use Verified Email Addresses

Always use verified email addresses when sending emails. Verified email addresses:

  • Improve sender credibility, ensuring your emails are trusted by recipient servers.
  • Reduce the likelihood of emails being flagged as spam or bounced.
  • Help maintain compliance with email authentication standards like SPF, DKIM, and DMARC.

Tip: Regularly verify your email addresses and domains within the email sender settings to ensure deliverability remains high.

Warm Up New Email Addresses

Gradually increasing the number of emails sent from new email addresses is essential for avoiding spam flags. This process, known as warming up, signals to email providers that your address is trustworthy.

  • Start with a low volume of emails per day (e.g., 20–30 emails).
  • Gradually increase the volume over several weeks.
  • Use the Email Ramp-Up feature in VanillaSoft to automate this process.
  • Focus on high-quality, personalized emails during the warm-up period to build a positive sender reputation.

Tip: Avoid sending bulk emails from a new address without warming it up, as this can quickly lead to blacklisting.

Enable Mailbox Rotation

Assigning multiple email addresses to a single user allows you to distribute sending volumes evenly, reducing the likelihood of spam flags.

  • Configure additional email addresses in the Email Senders section.
  • Set daily sending limits for each address to avoid overloading any single email account.
  • Use rotation to improve deliverability and ensure consistent engagement across campaigns.

Tip: Regularly review and adjust rotation settings to align with your campaign needs.

Avoid Spam Triggers

Email content plays a critical role in avoiding spam filters. Follow these guidelines to ensure your emails remain professional and trustworthy:

  • Personalize Emails: Use variables to address recipients by name or reference specific details.
  • Use Spintax: Add variations to your email content to avoid repetitive text that could trigger spam filters.
    For more information on Spintax, refer to the Spintax: Automate Email Variations for Better Engagement article.
  • Avoid Spam-Like Elements: Limit the use of excessive capitalization, multiple exclamation marks, or phrases commonly associated with spam (e.g., "Act now!" or "Guaranteed winner!").
  • Enable Email Tracking Carefully: While tracking email opens and link clicks can provide valuable insights, it can also impact deliverability. To configure tracking settings properly, see Configuring Email Tracking Settings.
  • Include an Unsubscribe Option: Provide recipients with a clear way to opt out of future emails to comply with anti-spam laws.

Tip: Before launching your campaign, test your email using spam checker tools to identify and resolve potential issues.

Monitor Email Metrics

Regularly reviewing email performance metrics helps you identify and address potential deliverability issues. Key metrics to monitor include:

  • Open Rate: Tracks how many recipients opened your email. A low open rate may indicate issues with subject lines or sender reputation.
  • Click-Through Rate: Measures how many recipients clicked links within your email. This metric highlights the effectiveness of your content and call-to-action.
  • Bounce Rate: Tracks undeliverable emails. High bounce rates may indicate outdated or invalid email addresses.
  • Unsubscribe Rate: Indicates the percentage of recipients opting out. Address content or targeting issues if this rate is high.

Tip: Use metrics to refine your email strategy, such as improving subject lines, testing new content, or optimizing sending schedules.
