How to Write Restock Email Subject Lines that Increase Open Rates?

Now, imagine you’re trying hard to bring back customers through a restock email alert, and your email subject line reads, ‘Back in stock’. How many subscribers do you think will open that email?

Did you know 69% of people mark emails as spam after reading subject lines?
