Top 50 Black Friday Email Subject Lines (2026)

Aim for under 50 characters so your hook survives mobile truncation during the year's most crowded inbox week. The average line in our Black Friday collection runs 43 characters, and the strongest are short and front-loaded: Lacoste's "50% OFF SITEWIDE." runs 18 characters, Patagonia's "Our Black Friday" just 16. Put the offer or hook in the first three or four words.

Most Black Friday subject lines we track skip emoji entirely and stand out with specifics or wit instead, like TUSHY's "UP TO 40% OFF SITEWIDE (tell your colon)." A single emoji can add contrast in a promo-heavy inbox, but it will not rescue a vague offer. If your brand uses emoji year-round, keep it; if not, Black Friday is a risky week to start.

Well before the day itself. Brands in our collection open early, like ClickUp's "Black Friday starts now: 25% off all Paid Plans," then escalate scarcity as stock moves, like Palermo House's "Almost gone: Outdoor at 30% off." A practical arc: tease in early November, launch the week before Thanksgiving, then send urgency-driven reminders through Cyber Monday.

In our archive, 24% of recent Black Friday subject lines name an exact percentage, so a specific number still differentiates; lead with it when the discount is strong. Curiosity works when the offer is modest or discounting is off-brand: Everlane's "You're Making Cashmere Even Better" and HOKA's "Best sellers for gifting" never mention a deal. Match the approach to the strength of your offer, not to a formula.
