Cross-brand promotion is one of the thorniest issues in e-mail marketing, mainly because many marketers don't see the potential traps.
When you promote your other brands to your customers the right way, you build a strong list of subscribers who are fans already of your other brands or sister companies or who found your Brand B a better fit than Brand A.
But you invite trouble when you assume that your Brand A subscribers automatically want messages about Brand B. Adding newsletters without getting explicit permission first is an opt-out strategy and forces your subscribers to say "Stop!" to you.
That's not a growth strategy. Instead, you set yourself up for more unsubscribes and spam complaints, which hurt your deliverability and can lower your overall marketing performance.
Wrong and Right Ways to Cross-Promote
I'm not saying you shouldn't cross-promote. Your current customers are your best resource, after all, since they already know you and, presumably, like the products you offer.
However, you get the best results - both in ROI (define) and deliverability - when you let your subscribers decide for themselves which e-mail messages they want to receive.
You probably have enough crossover among your market niches to justify cross-brand promotion, but not enough to start sending hardware deals to your sportswear shoppers.
Even if your company's divisions are complementary - flowers, gifts, and specialty foods, for example - you still shouldn't assume that your flower buyers also want your fruitcakes.
This problem goes beyond permission transfer or assuming interest. What if someone on the Brand A newsletter list previously opted out of Brand B e-mail or opts out of Brand A e-mail and expects all communication to cease?
Even scrubbing the list against Brand B's do-not-e-mail list doesn't solve the problem when people opt out of one list but continue to receive e-mail from others at the same company.
Legalities aside, this is underhanded and certain to backfire on you through unsubscribes, inactivity, and spam complaints.
Be sure what the permission subscribers agree to at opt-in matches what you explain in your privacy policy, and that a reasonable person would feel they understand what messages they will receive. Any ambiguity or questions mean you haven't set proper expectations and should revise your opt-in statement.
Cross-Promote Through High Visibility
So, now that I established a strong stand against cross-promoting without permission, here's how to do it right.
Without detracting from your primary message, keep your other options in front of subscribers, either to expand their subscriptions or as alternatives:
This increases visibility and also creates an atmosphere of credibility. If subscribers like your publications and want more of them, connecting the brands together will make them more likely to sign up.
You can even send a sample of another newsletter to your subscribers as part of your regular messaging schedule, with these safeguards:
Most likely, the content of each alternative newsletter will be somewhat different from your current one. The call to action should reflect this difference (for example, a bargain version of an upscale retail newsletter, or a men's version of a newsletter focused on women's interests).
One Last Thought
Go ahead and cross-promote your newsletters among your various audiences. Just be sure the registration reins remain in your subscribers' hands.
Until next time, keep on deliverin'!
