Email and SMS co-promotion
Borrow trust from a list that already listens

What Makes an Inbox Collab Work?
Strong email and SMS collabs feel like a useful recommendation, not a rented list.
Audience permission
Each brand sends to its own list. The partner gets exposure through endorsement, not through sharing customer data.
A partner-only offer
Give the audience a clear reason to click, such as an exclusive code, bundle, gift, or early-access drop.
Attribution by design
Use unique UTM links, partner codes, and send windows so both teams can measure traffic, orders, and revenue.
Your 4-Step Email & SMS Plan
This is one of the fastest collab types to launch when the assets and offer are clear.
1
Pick the promotion angle
Choose a dedicated feature, exclusive discount, bundled offer, or gift-with-purchase tie-in.
2
Swap approved assets
Share product photos, brand blurbs, hero copy, promo codes, links, legal notes, and sender requirements.
3
Coordinate the send
Decide whether to send simultaneously for an event feel or stagger sends to keep traffic manageable.
4
Review performance together
Compare opens, clicks, code redemptions, orders, unsubscribes, and revenue per recipient before repeating.
Inbox Plays to Try
Use a format that matches the strength of the relationship and the audience.
Brand We Love
Each brand sends a short endorsement of the other with a direct link to the partner's best entry product.
Best for awareness and trust.
Exclusive Code Swap
Both brands share a limited-time code built specifically for the partner audience.
Best for direct sales tracking.
Lifecycle Insert
Add the partner to a post-purchase, welcome, or replenishment flow where the context is strongest.
Best for evergreen promotion.
