Even corporate packages offered by Google have limitations that prevent mass mailings.<\/p>\n\n\n\n<p>For large-scale email distribution, specialized mail services (such as Amazon SES or Mailtrap) or platforms for creating, automating, and managing email campaigns\u2014known as <strong>Email Service Providers (ESPs)<\/strong>\u2014are essential. Within SFMC, the&nbsp;<strong>Email Studio<\/strong>&nbsp;application stands out as an advanced and feature-rich ESP solution that is available across all editions.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><a href=\"https:\/\/sii.pl\/blog\/wp-content\/uploads\/2024\/04\/Obraz1.png\"><img decoding=\"async\" width=\"710\" height=\"345\" src=\"https:\/\/sii.pl\/blog\/wp-content\/uploads\/2024\/04\/Obraz1.png\" alt=\"Salesforce Marketing Cloud Engagement \u2013 a snapshot of an omnichannel customer journey\" class=\"wp-image-27420\" srcset=\"https:\/\/sii.pl\/blog\/wp-content\/uploads\/2024\/04\/Obraz1.png 710w, https:\/\/sii.pl\/blog\/wp-content\/uploads\/2024\/04\/Obraz1-300x146.png 300w\" sizes=\"(max-width: 710px) 100vw, 710px\" \/><\/a><figcaption class=\"wp-element-caption\">Fig. 2 Salesforce Marketing Cloud Engagement \u2013 a snapshot of an omnichannel customer journey<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The path to recipients<\/strong><\/h2>\n\n\n\n<p>Internet service providers (ISP), email account providers (MBP), and organizations that monitor and filter spam are gradually tightening privacy protection rules and requirements for mass senders (e.g., Apple in 2022, Google and Yahoo! in February 2024). Both providers and users of mailing platforms must adapt&nbsp;to <strong>remain credible<\/strong> according to sender evaluation criteria and avoid being classified as spammers.<\/p>\n\n\n\n<p>A mass sender&#8217;s reputation is an essential indicator of credibility and trustworthiness<strong>.<\/strong> The ability to deliver messages from the sender to the recipient&#8217;s inbox is known as <strong>deliverability<\/strong>. While successfully delivering an email\u2014such as one promoting a band&#8217;s concert tour\u2014does not guarantee success, it serves as the initial step toward <strong>engaging<\/strong> a loyal fan who might click the link to purchase tickets. Deliverability directly impacts <strong>conversion<\/strong> rates, determining an email campaign&#8217;s return on investment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Sender reputation<\/strong><\/h2>\n\n\n\n<p>The sender&#8217;s reputation primarily stems from the credible source of the message. When utilizing the Salesforce ESP infrastructure, we can be confident that the provider&#8217;s servers <strong>(Mail Transfer Agent MTA)<\/strong> are trustworthy.

Assuming the organization&#8217;s primary domain is <strong>mojafirma.pl<\/strong>, it is recommended to specify a subdomain as the SAP Private Domain for sending from SFMC, such as <strong>mailing.mojafirma.pl.<\/strong> In addition, Salesforce recommends delegating this subdomain to Salesforce DNS servers (update DNS records in the subdomain&#8217;s hosting service).<\/p>\n\n\n\n<p>Choosing a subdomain for email marketing purposes safeguards the main domain, which may already be used for sending corporate emails, from a potential <strong>blacklisting<\/strong> by anti-spam filters.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><a href=\"https:\/\/sii.pl\/blog\/wp-content\/uploads\/2024\/04\/sfmc_authenticatedDomains.png\"><img decoding=\"async\" width=\"1024\" height=\"234\" src=\"https:\/\/sii.pl\/blog\/wp-content\/uploads\/2024\/04\/sfmc_authenticatedDomains-1024x234.png\" alt=\"Fig. 5 Salesforce Marketing Cloud Engagement \u2013 sender account setup\" class=\"wp-image-27428\" srcset=\"https:\/\/sii.pl\/blog\/wp-content\/uploads\/2024\/04\/sfmc_authenticatedDomains-1024x234.png 1024w, https:\/\/sii.pl\/blog\/wp-content\/uploads\/2024\/04\/sfmc_authenticatedDomains-300x69.png 300w, https:\/\/sii.pl\/blog\/wp-content\/uploads\/2024\/04\/sfmc_authenticatedDomains-768x176.png 768w, https:\/\/sii.pl\/blog\/wp-content\/uploads\/2024\/04\/sfmc_authenticatedDomains.png 1402w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">Fig. 5 Salesforce Marketing Cloud Engagement \u2013 sender account setup<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>SAP <\/strong>configuration<\/h3>\n\n\n\n<p>When configuring SAP, the Salesforce technical support team publishes DNS and rDNS entries, mapping the new domain to the sending server&#8217;s IP address and vice versa (PTR record). They also add records for the following:<\/p>\n\n\n\n<ol class=\"wp-block-list\" start=\"1\">\n<li><strong>Sender Policy Framework (SPF)<\/strong> \u2013 ensures that the sender&#8217;s IP address is authorized to send emails on behalf of the domain.<\/li>\n\n\n\n<li><strong>DomainKeys Identified Mail (DKIM)<\/strong> \u2013 provides cryptographic authentication for email messages.<\/li>\n\n\n\n<li><strong>Domain-based Message Authentication, Reporting, and Conformance (DMARC)<\/strong> \u2013 establishes basic rules (such as &#8220;reject&#8221;) to enhance sender authentication.<\/li>\n<\/ol>\n\n\n\n<p>Additionally, a freshly purchased and configured IP address and domain must gradually gain visibility among the wider public (known as&nbsp;<strong>IP and domain warm-up).<\/strong> Avoid unnecessary changes once a domain is configured, authenticated, and well-established.<\/p>\n\n\n\n<p>It&#8217;s worth noting that it is a good practice to separate marketing campaigns from transactional emails (such as password resets or purchase confirmations) by configuring separate IP addresses for each category. Transactional emails naturally have a high open rate, contributing to better deliverability.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><a href=\"https:\/\/sii.pl\/blog\/wp-content\/uploads\/2024\/04\/messageHeaderGmail.png\"><img decoding=\"async\" width=\"867\" height=\"230\" src=\"https:\/\/sii.pl\/blog\/wp-content\/uploads\/2024\/04\/messageHeaderGmail.png\" alt=\"Gmail \u2013 email header\" class=\"wp-image-27430\" srcset=\"https:\/\/sii.pl\/blog\/wp-content\/uploads\/2024\/04\/messageHeaderGmail.png 867w, https:\/\/sii.pl\/blog\/wp-content\/uploads\/2024\/04\/messageHeaderGmail-300x80.png 300w, https:\/\/sii.pl\/blog\/wp-content\/uploads\/2024\/04\/messageHeaderGmail-768x204.png 768w\" sizes=\"(max-width: 867px) 100vw, 867px\" \/><\/a><figcaption class=\"wp-element-caption\">Fig. 6 Gmail \u2013 email header<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">From name<\/h2>\n\n\n\n<p>Once you have an authenticated email domain, create a sender profile that will appear in the message header (From:).

The sender&#8217;s name should be recognizable and trustworthy because it is the first visible element in a crowded inbox.<\/p>\n\n\n\n<p>Adding the sender&#8217;s address to the Safe Senders List or Adress Book ensures that subsequent messages to that subscriber will directly land in the inbox folder.
