Note: Most email platforms only track forwards made via a tracked forward-to-a-friend link. Organic forwards (using native email forward button) are not counted and actual forwarding rates are typically higher than reported.
How Forwarding Rate is Calculated
Forwarding Rate = (Forwards ÷ Emails Delivered) × 100
Additional Reach = Forwards × Avg Recipients Per Forward
Total Reach = Emails Delivered + Additional Reach
Most email platforms track forwards via a special forward-to-a-friend link in the email. Recipients who forward using their native email client are not tracked, so actual forwarding rates are often higher than reported numbers suggest.
Email Forwarding Rate: Measuring Organic Reach and Content Virality
Email forwarding rate measures the percentage of email recipients who liked your content enough to share it with someone else. It's one of the strongest positive engagement signals in email marketing — a subscriber who forwards your email is actively advocating for your content to someone in their personal or professional network. This organic reach represents audience expansion you don't have to pay for.
Forwarding rates are typically very low — most campaigns see rates below 0.1% — so even small improvements represent meaningful audience growth. Content-heavy newsletters, educational material, exclusive deals, and genuinely funny or surprising emails consistently outperform standard promotional sends on forwarding rate. If you want subscribers to share your emails, design for shareability: clear value, easy-to-read content, and an explicit invitation to share.
Forward-to-a-Friend vs Native Forwarding
There are two types of email forwards: tracked forwards via a special forward-to-a-friend link (which your email platform can count), and native forwards using the recipient's email client forward button (which are invisible to tracking). Most email platforms only report tracked forwards, which means actual forwarding rates are almost always higher than the numbers you see in your dashboard. Including a clearly marked "forward to a friend" link in your emails improves trackability and encourages intentional sharing.
How to Increase Email Forwarding Rate
Include an explicit call to action to share: "Know someone who'd find this useful? Forward it on." Place the forward link near the top of the email, not just in the footer. Create roundup emails, digest formats, or curated content that readers naturally want to share with colleagues or friends. Exclusive deals with a "share this with a friend" hook can turn forwarding into a referral mechanic. Track which content types and topics produce the highest forward rates, then create more of them.
