Cold email subject lines a store owner will read

What a subject line has to do

This guide is part of our retail outreach guide for food and beverage brands. A subject line has one job: get the email opened by the right person. It does not need to sell the product. It needs to look like a note from a real person about their store, not a newsletter or a sales blast.

The owner decides in the half second it takes to scroll past, and a specific line wins that half second more often than a clever one.

The rules

These rules come from years of writing to stores, and they are the ones LaunchPal follows when it writes a subject line for each store.

• Keep it short. Three to seven words. Most people read email on a phone, which cuts long lines off.
• Make it about them. The store's name, its street or its area does more than any adjective.
• Say what it is. A cold brew, a chilli oil, a soju. Not a new opportunity.
• Write in lower case, like a person. Title Case and capitals look like marketing.
• Leave out the sales words. Free, offer, deal, limited, exclusive and exclamation marks make the email look like a promotion, and can count against it with spam filters.
• Do not fake it. No Re: on a first email, and no subject that pretends you have met. Owners notice, and it ends the conversation before it starts.

Examples by store type

Swap in your product and the store's details. Each one names the product and the store, and nothing else.

• Café: a cold brew for [café name]'s fridge
• Café: oat milk iced tea for [suburb] cafés
• Deli: small-batch chilli oil for [store name]
• Grocer: a local granola for your breakfast shelf
• Bar: a soju serve for [bar name]
• Bottle shop: a [region] gin RTD for [store name]
• Hotel: a local tonic for [hotel name]'s bar
• Health food store: low-sugar snack bars for [store name]

Should a subject line be a question?

Sometimes. A real question about the store works: room in your fridge for a local kombucha? It invites a one-word answer and says what the email is about. A vague one does not: have you got a minute? reads like a trick to get the email opened, and the owner feels it when the pitch arrives.

If you use a question, make sure the email answers it in the first line. The subject line and the opening line should read as one thought.

Details that make a subject line feel personal

The detail that earns the open is usually something the owner chose themselves. A few that work well:

• Their street or suburb: a local kombucha for [street] cafés.
• Something they already stock: next to your local hot sauces.
• Their kind of venue: for your natural wine list.
• Their season: a cold brew for your summer menu.

The first line counts as part of the subject

Most inboxes show the first few words of the email under the subject line. Make them count. If the email opens with a line about the store, the owner sees that line before they decide to open it. If it opens with I hope this email finds you well, they see that instead.

Subject lines that get deleted

These all appear in real inboxes every week. Each one tells the owner it is a sales email before they open it.

• An exciting opportunity for your store. Vague, and every store owner has learned what it means.
• Quick question? Overused, and a little dishonest when the email is a pitch.
• FREE SAMPLES FOR YOUR STORE!!! Capitals, sales words and exclamation marks: the spam folder in one line.
• Introducing [brand name]. About you, not them. The owner does not know your brand yet.
• Following up on a first email. Confusing, and it reads as a trick.

Subject lines for follow-ups

A follow-up can sit in the same thread as the first email, so the owner sees the whole conversation in one place. If you start a new thread, keep the subject just as specific: a nearby stockist or a serving idea makes a better line than following up. Our guide to the follow-up email after no response covers what goes inside.

Test one thing at a time

If you want to know which subject line works better, change only the subject line, send to similar stores in the same city, and wait for the whole sequence to finish before you compare. Replies are a better measure than anything else, because a reply is the thing you want.

The LaunchPal campaign report breaks replies down by step and by subject line, so you can see which lines earn answers. Each store's subject line is written for that store, the same way its email is. More in personalised outreach emails. For the body that follows the subject line, see the cold email templates for retailers.

Where the subject line comes from matters too

The best subject line still lands in spam if the email comes from a brand-new domain sending hundreds of emails on its first day. We buy a separate sending domain for each brand, warm it slowly and send at a steady pace, so the subject line gets seen in the inbox and your own domain is never at risk.
