How do I write subject lines for a small seller's email?

What a subject line must do

A subject line has a single job: tell the reader what is inside, so she can decide whether to open. For a small seller whose readers know her name, being clear is more useful than being clever.

Say what the email is about. Say it in plain words. Keep it short enough to read on a phone without cutting off.

Patterns that stay honest

Here are patterns you can borrow. Change the words to suit your products.

• The news: "New batch of cold-pressed oils is ready"
• The restock: "The cotton tote is back in stock"
• The story: "How we make our brass lamps"
• The tip: "Three ways to wear a block-print dupatta"
• The reminder: "Orders for the Diwali box close on Friday"
• The thank-you: "Thank you for a good month"
• The question: "Which colour should we make next?"

Each tells the reader exactly what she will find. That respect is what builds the habit of opening.

Use your name

If your list knows you, putting your brand name or your first name in the sender field helps people recognise you. A friendly "Meena from Kalpavriksha" in the sender line is better than a vague company name. The subject line then carries the news.

Keep a check on length

Short is easier. If you can say it in six or seven words, do. If you need more, put the most important words at the start, in case the end is cut off on a small screen.

Avoid these traps

• Capital letters and many exclamation marks; they feel like shouting
• Fake urgency, such as "Last chance" when it is not
• Misleading hints, like "Re:" or "Fwd:" to look like a reply
• Promising something the email does not deliver
• Emoji and symbols, if your readers would find them odd; stay plain

A misleading subject line may get an open once, but you will lose trust. Your list is small, so trust is your asset.

Match the subject to the first line

The first line of the email should continue the subject line. If the subject says "The cotton tote is back", the first line should say so and show it. Do not make readers hunt.

Try, notice, adjust

You can try two phrasings on different groups of your list and see which one gets more replies. But with a tiny list, the numbers are small, so treat results as hints, not proof. Do not quote open rates as facts; you do not know how any pattern would perform for another brand.

Keep a swipe file

Whenever an email from a brand you admire catches your eye for being clear, write down the subject line in a note. Over time you build a small collection of patterns. Combine it with how to write a newsletter for a tiny brand and a clear welcome email, and your inbox presence will feel like one honest voice.
