What the winners had in common.

Wellness brands, restaurants, a public radio station and a chocolate maker. Different businesses, the same few decisions. These are the patterns behind every result on this page, and the ones we build into every Mailchimp account we run.

They stopped sending to everyone: Every winner replaced whole-list blasts with segments built on purchases, interests, location or the step a customer was on. Relevance lifted opens, clicks and inbox placement together.
They let automation do the follow-up: Welcome series, abandoned carts, stalled applications and win-backs ran on their own through automation flows, earning every day without anyone pressing send.
They connected their data: Shopify, PrestaShop, HubSpot or a custom API: each program fed real customer data into Mailchimp, so every message matched what the person had actually done.
They added text where timing matters: Restaurants, fundraisers and stores with flash sales used SMS for messages that cannot wait, alongside email rather than instead of it.
They tested before they scaled: Head-to-head SMS tests, A/B tested subject lines and multivariate flows. The winners proved what worked before putting more behind it.

Your business, the same playbook.

These results come from businesses of every size, and the ideas behind them scale down as well as up.
