Mailchimp × Birdcall

Mailchimp x Birdcall, SMS unblocks time-sensitive offers

Why it works

The demand was already there: 163,000 opted-in subscribers and proven promotion concepts. The single constraint was channel latency. Social algorithms, email clutter, and push notification opt-outs were burying time-sensitive offers before customers could act. Removing that constraint via SMS short code produced a clear step-change: 50% of total digital engagement within two months. The story leads with SMS as a category rather than Mailchimp as a vendor, making it Category-proof first and ROI-proof second through the 16.1% click rate comparison.

Steal this

The direct channel comparison (SMS 16.1% click rate vs. email 1.5%) is a single, concrete number that makes the category argument without any editorial spin. Pair your new channel metric against the incumbent in the same sentence.
