Upsell free subscribers to your paid newsletter by teasing each new piece of content.

If your newsletter has both a paid and a free version, you can up your chances of paid conversions with a simple email. Pique your readers' interest with a quick message about each piece of paid content that you put out.

When it comes to paid newsletters, it's usually easier to upsell a free subscriber than it is to land someone new. Entice your readers with an email that includes a few details about the paid content that you just published. Keep it short. Add a clear call-to-action to become a paid subscriber. Let them know that there's no pressure — you'll keep sending them stellar content either way. And just in case, give them a super-easy way to opt out of these emails without unsubscribing from the entire newsletter.
