Grow your email list faster with proven cross-promotion tactics and partnerships that work in 2025.

Sometimes the best way to grow your email list isn’t solo — it’s strategic collaboration.
Cross-promotion connects you with warm, aligned audiences from other creators, brands, or platforms — multiplying your reach without doubling your budget or effort.
In 2025, savvy marketers are using cross-promotions to add hundreds (or thousands) of quality subscribers in just one campaign. Let’s explore the top ways to make this work — and avoid common pitfalls along the way.
Cross-promotion is a marketing collaboration where two or more brands promote each other’s content, product, or offers to their respective audiences — often in a mutually beneficial, non-competitive way.
In email marketing, this usually means:
Promoting each other’s lead magnets
Featuring guest content or shout-outs
Running joint events (webinars, giveaways, etc.)
Swapping newsletter mentions

✅ Tap into pre-built, trusting audiences ✅ Lower cost per lead than ads ✅ Build brand authority through association ✅ Foster long-term partnerships ✅ Expand into related verticals
The key? Find partners with aligned audiences but non-overlapping offers.
Giveaways are still effective — especially when run with the right partner.
How to do it:
Choose a relevant, high-value prize (tools, access, resources)
Create a shared landing page or form
Promote across both brands’ lists, socials, and blogs
Collect emails and follow up with welcome sequences
Offer bonus entries for referrals or social shares
Example: “Inbox Mastery Toolkit Giveaway – Hosted by SenderWiz + ColdEmailExperts”
🎯 Tip: Always clearly state how emails will be used (GDPR compliance).
One of the simplest and most effective tactics.
Each partner features the other in their newsletter with:
A short blurb
Lead magnet link or call to action
Clear value proposition
💬 Example: "If you love our cold email tips, you’ll also enjoy [Partner]'s weekly inbox hacks — sign up here."
Great when you have similarly sized and engaged lists.
Write a guest post, appear on a podcast, or contribute to a YouTube video — and include your lead magnet.
✅ What to include:
Quick introduction with credibility
Actionable value
Mention of your free resource (with link)
Optional tracking link or UTM for analytics
Platforms love fresh content — and you gain evergreen exposure.
This tactic builds trust fast — and lets you co-promote to both lists.
Step-by-step:
Choose a focused topic aligned to both audiences
Co-brand the registration page and confirmation emails
Split promotion responsibilities
Deliver valuable, non-salesy content
Follow up with replay + bonus content from both brands
Everyone who registers is added to both lists (with proper consent).
SenderWiz tags and automates follow-up flows based on signup and attendance behavior.
Place your partner’s freebie or tool as a resource inside:
Your PDF guide
Lead magnet checklist
Thank-you page after signup
Confirmation email with extra bonuses
It’s low-friction and delivers reciprocal value over time.
Look beyond competitors. Consider:
SaaS companies with overlapping users
Niche influencers or creators
Course creators or educators
Affiliate marketers or consultants
Build partnerships based on:
Shared values
Content alignment
Audience trust
SenderWiz supports tagging and tracking by signup source, helping you identify which partnerships deliver the best quality leads.
Build a co-branded resource collection or multi-part email series delivered across both lists.
Examples:
“7 Days to Better Deliverability” Series
“The Complete Email Toolkit for B2B Marketers”
“Cold Outreach Content Vault”
This boosts engagement and increases exposure for both parties.
✅ Be transparent with email sharing and consent ✅ Promote partners you genuinely respect ✅ Use UTM parameters to track opt-in performance ✅ Always lead with value, not just an ask ✅ Follow up with real appreciation and collaboration
📉 Avoid:
Spamming each other's lists
Unclear value propositions
One-sided efforts with no follow-through
Brands: A cold email SaaS + deliverability consultant Strategy: Co-hosted “Inbox Success Live” 1-hour training Promotion: 3 emails + LinkedIn + Twitter threads
Results:
2,400 signups
75% email open rate post-webinar
1,800 net new subscribers across both brands
11% trial conversions within 7 days
✅ Cross-promotion = reach + results.
You don’t have to build your email list alone.
With the right partners, you can create win-win campaigns that double your visibility, build credibility, and attract the kind of subscribers who actually want what you offer.
Start small. Collaborate wisely. And always lead with value.
