The Salesforce playbook

Salesforce sends at scale. Your domain still has to earn the inbox.

Marketing Cloud authenticates a private sending domain with SPF, DKIM and DMARC, and offers dedicated IPs for larger senders. Salesforce is clear that a new dedicated IP is warmed by the sender, and a new domain starts with no history either. Keep your journeys and sends exactly where they are. Add the domain here and we build its reputation while Salesforce keeps sending.

The Salesforce playbook

Keep sending from Salesforce. Warm the domain here.

Step 1

Authenticate a private domain in Marketing Cloud

Without a Private Domain or the Sender Authentication Package (SAP), Marketing Cloud Engagement sends on Salesforce-operated domains rather than yours. A Private Domain adds SPF, DKIM and DMARC for your sending domain; SAP bundles it with a dedicated IP, link branding and reply mail management.

Step 2

Know what Salesforce warms, and what it does not

Salesforce says there is no such thing as a pre-warmed IP: a new dedicated IP is warmed by the sender, raising volume gradually and pausing if engagement drops. That guidance is about the IP. The domain carries its own reputation, and on shared IPs it is the only one that is yours.

Step 3

Add your brand domain to Inbox Boost

Use the domain in your From address, yourbrand.com. Any private sending subdomain you set up in Marketing Cloud stays with Salesforce. We set up what it needs and build its sender reputation. Nothing to connect to Salesforce: no API key, no connected app, no change to your account.

Step 4

Keep every journey and send running in Salesforce

Journeys, triggered sends, newsletters: all of it stays in Marketing Cloud. Mailbox providers score the domain in your From address, so the reputation built here counts for every Salesforce send from yourbrand.com.

Step 5

Check where Salesforce mail lands

Inbox placement tests show whether your sends reach Primary, Promotions or Spam across the major mailbox providers, and blacklist monitoring keeps watching the domain once it is warm.

  • Nothing to connect: no Salesforce API key, connected app or package
  • Nothing to change: journeys, data extensions and templates stay exactly as they are
  • Shared or dedicated IP: it works either way, because the reputation belongs to the domain
  • Watched after warmup: blacklist and authentication monitoring on your brand domain

Questions

Salesforce questions, answered.

Does Inbox Boost connect to my Salesforce account?
No. There is no API key, connected app or package to install. Inbox Boost works on your brand domain, and Salesforce keeps sending your journeys and campaigns exactly as it does now.
I have a dedicated IP in Marketing Cloud. Why warm the domain too?
Salesforce’s warming guidance is for the IP, and it is clear the sender does that warming: there is no pre-warmed IP. Your brand domain carries its own reputation with Gmail, Outlook and Yahoo, separate from any IP, and building it here helps whichever IP Salesforce sends from.
I am on Marketing Cloud’s shared IPs. Does this still help?
Yes. Salesforce describes shared IP reputation as pooled with other Marketing Cloud Engagement customers, so the domain is the reputation that is actually yours. Building it here helps every send Salesforce makes from it.
Do I need a Private Domain or SAP first?
We recommend it. Without one, Marketing Cloud sends on Salesforce-operated domains, so the reputation your mail earns is not tied to your brand. Set up the private domain in Salesforce, then add your brand domain, the one in your From address, here. Any private sending subdomain stays with Salesforce.
Can I see whether it is working?
Yes. Inbox placement tests show where your Salesforce mail lands, Primary, Promotions or Spam, across the major mailbox providers, and blacklist monitoring keeps watching the domain afterwards.
