Sender Profile, Delivery Profile, Send Classification: What Each Does

New client onboarding, typical request: "Make sure emails send from orders@company.com, show From as Company Store, use a separate IP for transactional email, and follow CAN-SPAM Transactional rules."

Four requirements. Three different SFMC settings in three different screens to satisfy them. It's the single most confusing area for engineers new to Marketing Cloud.

Here's what each setting controls and where it lives.

Sender Profile - what the subscriber sees

Sender Profile defines the From Name and From Email Address - the identity the subscriber sees in their inbox.

An account can have multiple Sender Profiles:

• One for marketing (newsletter@company.com)
• One for transactional (orders@company.com)
• One per brand, if the client operates multiple brands

Advanced pattern: if the client wants From Name to vary per subscriber (show the assigned sales rep's name), the Sender Profile can be configured as dynamic and populated by AMPscript at send time.

Lives at: Email Studio > Admin > Sender Profiles

Delivery Profile - what the ISP sees

Delivery Profile defines the IP address and sending domain used for the send - the infrastructure underneath that the subscriber doesn't see but every ISP does.

Why multiple Delivery Profiles? Because most clients have at least two classes of email with different reputation profiles:

• Commercial (newsletters, promotions): high volume, variable engagement, uses one IP
• Transactional (order confirmations, password resets): high open rate, near-zero complaints, deserves a separate IP

Separating IPs prevents commercial reputation problems from dragging down transactional deliverability. If commercial gets throttled, transactional still lands inboxes.

Send Classification - the combined bundle

Send Classification packages a Sender Profile + Delivery Profile + a CAN-SPAM classification into a single selectable unit used at send time.

CAN-SPAM classification is either:

CommercialTransactionalPurposeMarketing, promotionConfirm transaction, service communicationUnsubscribe linkRequiredNot requiredCan send to unsubscribed subscribersNoYes (if genuinely transactional)ExampleNewsletter, flash saleOrder confirmation, password reset

When setting up a Send Classification for order confirmations, choose Transactional. SFMC will then deliver to contacts who have previously unsubscribed - which is what you want for receipts and service notifications.

The mental model

At actual send time, you only pick a Send Classification. It pulls in the Sender + Delivery automatically.

Three mistakes we still see

Mistake 1: Trying to change the IP from Sender Profile

Team wants a different IP for a specific send, opens Sender Profile looking for an IP field. There isn't one. IP lives in Delivery Profile. Took most of a morning for one engineer to find this the first time.

Mistake 2: Commercial classification on order confirmations

Order confirmation email goes out with Commercial classification. Unsubscribed customers don't receive their receipts. Client's customer service team fields complaints for two days before the root cause is found.

Transactional emails - receipts, shipping notifications, password resets, OTPs - need a Send Classification marked Transactional. Create one during onboarding; don't reuse the default Commercial classification for anything service-related.

Mistake 3: Unverified From Address

Team builds a campaign sending from orders@company.com. The send fails because the domain hasn't been verified in From Address Management. SFMC requires domain verification before any new From address can be used.

Setup: Email Studio > Admin > From Address Management. Verify domains early in onboarding so this doesn't block go-live.

Takeaway

Three settings, three purposes, three screens. Sender Profile is what the subscriber sees; Delivery Profile is what the ISP sees; Send Classification is what you actually pick at send time. Get them right during onboarding - retrofitting transactional/commercial separation after volume is live is harder than setting it up day one.
