Understanding Email Send Limits in SFMC

The guideline for email send limits in SFMC is 2 million emails per day per IP address, as stated in the Salesforce documentation. However, this is not a hard limit, and the actual send capacity may vary depending on several factors, including the quality of the email list, the reputation of the sender, and the configuration of the email campaign.

The root cause of deliverability issues is often related to the sudden spike in email send volume, which can be perceived as suspicious by ISPs and lead to blacklisting or spam filtering.

To avoid this, it is essential to warm up the IP address gradually, increasing the send volume over time to allow the ISPs to recognize the sender as legitimate. Additionally, it is crucial to monitor the email campaign’s performance, tracking metrics such as bounces, complaints, and spam reports to identify potential issues early on.

Best Practices for High-Volume Email Sends

When sending large volumes of emails, it is essential to follow best practices to maintain high deliverability rates. This includes:

• Obtaining consent from the recipients
• Using a high-quality email list
• Warming up the IP address gradually
• Monitoring the email campaign’s performance
• Configuring the email campaign to use a reputable sender domain

By following these best practices and understanding the guidelines for email send limits in SFMC, teams can optimize their email send volume to maintain high deliverability rates and avoid blacklisting or spam filtering.

Configuring Journey Builder for High-Volume Email Sends

To configure Journey Builder for high-volume email sends, teams can use the High-Throughput Sending (HTS) feature, which allows for higher send volumes. However, this feature should be used with caution, as it can increase the risk of blacklisting or spam filtering if not configured correctly.

Journey Builder Configuration

/* Example Journey Builder configuration */
var email = {
  "subject": "Example Email",
  "htmlBody": "Example HTML Body",
  "textBody": "Example Text Body",
  "from": {"name": "Example Sender", "email": "[email protected]"}
};

Heads up: When using HTS, it is essential to monitor the email campaign’s performance closely to avoid any potential issues.
