This guide cuts through the complexity, offering clear steps on setting up, navigating sending limits, tracking successes, and solving common email issues with Salesforce. Ready to make every email more effective and your marketing strategy sharper? Let’s get started.

    What Are Salesforce Outbound Emails?

    Salesforce outbound emails are dynamic tools designed to launch your messages directly into your customers’ inboxes, right from the Salesforce platform. These emails aren’t just about communication; they’re about creating lasting connections, delivering personalized content, and driving engagement directly tied to your business goals.

    In the sphere of CRM and marketing, the role of Salesforce outbound emails is crucial. They empower you to directly influence your marketing outcomes by enabling targeted, meaningful interactions with your audience. From nurturing leads to boosting sales and strengthening customer loyalty, these emails are your direct line to achieving tangible results. With every targeted message, newsletter, or promotional offer sent, you’re not just reaching out; you’re driving action, fostering relationships, and paving the way for measurable success.

    Configuring Salesforce Outbound Emails

    TLS Configuration


    Transport Layer Security (TLS) safeguards your email communication by encrypting the data sent between your Salesforce instance and the recipient’s email server.

    How to Enable:

      1. Navigate to Setup in Salesforce.
      2. Enter Email Relay Activation in the Quick Find box and select it.
      3. Enable TLS by checking the Enforce TLS option to ensure all outbound emails are encrypted.

    DKIM Setup


    DomainKeys Identified Mail (DKIM) provides an encryption key and digital signature that verifies your emails are not tampered with and actually come from your domain.

    How to Configure:

      1. In Setup, search for DKIM Keys in the Quick Find box and select it.
      2. Click New to create a DKIM key.
      3. Enter a Selector and Domain. The selector is a unique identifier for the DKIM key, and the domain is your organization’s email domain.
      4. Generate the DKIM key and add the provided DNS records to your domain’s DNS settings to complete the verification process.

    Email Templates

    Custom email templates enable you to send personalized and consistent communications to your customers.

    How to Manage:

      1. Go to Setup, search for Email Templates in the Quick Find box, and select Classic Email Templates or Lightning Email Templates depending on your Salesforce interface.
      2. Click New Template to create a new template or edit an existing template to customize it according to your campaign’s needs.
      3. Utilize the rich text editor or HTML editor for detailed customization, incorporating your branding and message effectively.

    Sending Domains and IP Addresses


    Verifying your sending domains and IP addresses improves email deliverability by marking them as trusted sources.

    How to Verify:

      1. In Setup, search for Sender Authentication Package (SAP) in the Quick Find box, and select it.
      2. Use the Domain Management section to add your domain and follow the steps to verify ownership by adding DNS records provided by Salesforce to your domain’s DNS settings.
      3. If applicable, configure your SPF records to include Salesforce’s IP addresses, enhancing the legitimacy of your emails.

    Limitations of Sending Salesforce Outbound Emails

    Daily and Monthly Email Sending Limits

    To maximize the impact of your Salesforce email campaigns, it’s essential to navigate the platform’s email sending limits wisely. Salesforce sets these caps to ensure fair usage and system stability, with the limits tailored to different editions and recipient types.

    Understanding Your Email Sending Capacity

    • For Emails Sent to Internal Users. Unlimited in most Salesforce editions, allowing for free communication within your organization.
    • For Emails Sent to External Addresses:
      • Essentials, Professional, Enterprise, Performance, and Unlimited Editions. The limit is 5,000 emails per Salesforce license per day. The count is based on the total number of licenses, not just those in use.
      • Developer Edition. Limited to a maximum of 15 email sends per day to external addresses, primarily for testing purposes.

    How to Check Your Specific Limits

    • Salesforce Documentation. Salesforce regularly updates its documentation to reflect current limits. Accessing the Salesforce Help documentation or the Salesforce Developers website provides the most up-to-date information.
    • Your Account Settings:
      • Navigate to Setup in your Salesforce account.
      • Use the Quick Find box to search for “Email Limits.”
      • Here, you can view detailed information about your account’s specific email sending capabilities, including any daily or monthly restrictions.

    Size Limits for Emails and Attachments

    Salesforce sets clear boundaries on the size of emails and attachments to ensure smooth delivery and maintain system performance.

    Email Size Limits

    • Overall Email Size. Salesforce caps the total size of an email (encompassing the email body, headers, and attachments) at 25 MB. Attempting to send an email that exceeds this size could prevent it from being delivered.

    Attachment Size Restrictions

    • Maximum Attachment Size. While the overall email size limit is 25 MB, it’s recommended to keep individual attachments well below this threshold to enhance deliverability. Aim for attachment sizes that are significantly smaller to account for encoding overhead, which increases the size by approximately 33%. Thus, keeping attachments under 5 MB each is a good rule of thumb to ensure they pass through most email systems without issues.

    Limitations Related to the Content and Formatting of Emails

    Optimizing Email Content and Formatting

    • Complex HTML emails or those heavy with images might face delivery challenges. Aim for a balance between engaging visuals and simplicity to ensure compatibility across email clients.
    • Be mindful of the types of files you attach. Opt for commonly used formats and avoid excessively large attachments to prevent delivery issues.

    Navigating Through Spam Filters

    • Spam filters scrutinize emails for certain red flags. To improve deliverability, avoid using language that sounds overly promotional, excessive links, or known spam trigger words in both your email’s subject line and body.
    • Focus on creating content that resonates with your audience. Emails with high engagement rates are less likely to be flagged as spam, enhancing your overall deliverability.

    Best Practices to Optimize Email Delivery Within These Limitations

    To maximize the effectiveness of your Salesforce email campaigns within the platform’s limits, focus on strategies that enhance deliverability and engagement. 

    Tailor Your Audience

    • Segmentation. Break down your email lists into specific groups based on customer behavior, preferences, or demographics. Targeted campaigns ensure you’re not only adhering to email limits but also significantly boosting engagement by reaching the right audience with the right message.

    Streamline Your Emails

    • Size Matters. Keep your emails lean by optimizing images (consider compression tools) and linking to external content rather than attaching large files. This practice not only helps with staying under size limits but also improves load times for recipients, enhancing user experience.

    Ensure Compatibility and Deliverability

    • Pre-Send Testing. Use testing tools to preview your emails across different devices and email clients, ensuring your message looks as intended everywhere. This step is crucial to avoid formatting issues that could affect readability and engagement.
    • Spam Check. Run your emails through spam analysis tools to identify potential red flags that could hinder deliverability. Adjusting content based on these insights can improve your chances of reaching the inbox.

    Analyze and Adjust

    • Performance Monitoring. Keep a close eye on key metrics like open rates, click-through rates, and bounce rates. Regular analysis allows you to pinpoint what works, what doesn’t, and where there’s room for improvement, enabling you to refine your strategy for better results.

    Tracking Salesforce Outbound Emails

    Essential Metrics for Targeted Results

    Zero in on these metrics to directly impact your campaign outcomes:

    • Open Rates. Critical for assessing the immediate appeal of your emails. Optimize your subject lines for maximum impact.
    • Click-Through Rates (CTR). Measure the effectiveness of your content and call-to-actions (CTAs), refining them to boost engagement.
    • Bounce Rates. Keep your email deliverability high by identifying and resolving issues that prevent emails from reaching their targets.

    The Strategic Advantage of Tracking Emails

    Tracking provides invaluable insights that drive tangible improvements:

    • Boost Engagement. Tailor your content based on what captivates your audience, directly enhancing interaction with your emails.
    • Ensure Deliverability. Maintain a pristine email list and adjust content to avoid spam filters, ensuring your messages land in inboxes.
    • Make Informed Decisions. Leverage data from email metrics to fine-tune your campaigns, optimizing for better performance and higher ROI.

    Implementing Email Tracking for Impact

    Activate and utilize Salesforce’s email tracking features to transform insights into actions:

    1. Initiate Tracking. Access the Setup menu in Salesforce, search for “Email Tracking,” and enable the feature to start gathering data on open rates, CTR, and more.
    2. Analyze and Adapt. Use Salesforce’s reporting tools to monitor these metrics. Identify trends and patterns, and adjust your campaigns accordingly for better results.
    3. Continual Optimization. Regularly review your email performance. Utilize feedback loops to constantly refine your strategy, aiming for higher engagement and conversion rates.

    Troubleshooting Common Issues

    Efficiently resolving common Salesforce outbound email issues ensures your campaigns deliver optimal results

    Streamlining Attachment Handling

    • Manage Size Limits. Keep email sizes under 25 MB. For larger files, use cloud storage links.
    • Ensure Compatibility. Opt for common file formats (PDF, DOCX, JPEG) to avoid opening issues on the recipient’s end.

    Navigating XLSM File Challenges

    • Excel Macro-Enabled Workbook (XLSM) files can be particularly tricky due to security concerns:

      • Email Filters and Blocks. Some email clients or security systems may block XLSM files due to the potential for macros to contain malware. To circumvent this, consider converting XLSM files to PDFs for distribution, or share them via secure cloud storage links, providing access within the email.
      • Informing Recipients. If sending XLSM files is unavoidable, clearly communicate with your recipients about why they’re receiving this file type and how to safely access it. This can involve instructions for downloading or verifying the file’s safety.

    Quick Fixes for Other Issues

    • Update Email Lists. Regularly cleanse your list to prevent bounces from invalid addresses.
    • Avoid Spam Traps. Use straightforward language and maintain a good sender reputation to stay out of spam folders.
    • Monitor Deliveries. Check delivery reports for insights on how to improve email reach and effectiveness.
