Boost Back-in-Stock & Waitlist Emails with Social Proof Counters

When a favorite comes back, show subscribers how many others are looking at it, live, inside the email.

Let Real Demand Do the Talking

A restock email goes to people who already wanted the product. Showing how many others are looking at the same email reminds them it sold out once already.

Sendtric's social proof counters show live view and click counts inside the email, based on real engagement with your send.

Example: A Sneaker Restock

Here is how a footwear brand could use counters in a back-in-stock email:

  • A Views counter shows how many times the restock email has been viewed.
  • An Opens counter on the Get Yours button shows how many people have clicked through to buy.
  • A minimum threshold keeps each counter hidden until the numbers are worth showing.
  • If the product sells out again, update the button's dynamic link to point at the waitlist instead.

Social Proof in Restock Emails: What Works

  • Email your waitlist first. Send the restock to people who asked to be told before your wider list. Their views and clicks build the count, so it is past your threshold by the time everyone else receives it.
  • Show demand with clicks. An Opens counter on your button counts clicks through to the product, a strong signal of interest that encourages others to follow.
  • Let demand create the urgency. A rising live count shows shoppers that others want the product too, which adds natural urgency and helps turn a returning favorite into quick sales.
  • Plan for selling out again. Point the button's dynamic link at the waitlist the moment stock runs out, and every email you have sent follows.
  • Lead with the product. The restock is the news. Put the counter below the product image and above the button, where it supports the decision to buy.
