How to send a cold email to every local business in a city: method, tool and rules

Sending cold emails to local businesses in a city takes three steps: build the list (one trade, one city, valid email addresses), write one short personalised email, then send it gradually from a real address with an unsubscribe link. This guide covers each step, with the rules that keep your emails out of spam and within GDPR.

Why email works with local businesses

A restaurant owner or a hairdresser rarely picks up the phone between customers, but they read their emails in the evening or before opening. Email has three advantages for a salesperson, a freelancer or a coach:

• it scales: one well-written message can go to 100 or 200 businesses the same day;
• it leaves a trace: the owner can reply when they have time, forward it to a partner, or come back a month later;
• it warms up the call: "I emailed you on Tuesday about your website" opens a conversation far more easily than a cold call.

A concrete example: in Annecy, Prospya lists 293 restaurants, 168 of them with an email address. That is a full campaign, written once.

Step 1: build the right list

The list is half the result. Three things matter:

1. One trade, one area: "restaurants in Annecy" or "hair salons in Lyon" (360 salons, 166 with an email) rather than "businesses in France". Your message can then talk about the trade.
2. Emails that exist: a well-formed address whose domain really receives email. Sending to dead addresses ruins your sender reputation.
3. No duplicates, nobody who said no: remove businesses you already contacted and anyone who unsubscribed.

In Prospya, a search for "restaurants in Annecy" shows how many businesses have an email, and only verified addresses (format + active domain) are kept for a campaign. See also how to find a business email.

Step 2: write an email that gets replies

A cold email to a shop owner should fit on a phone screen:

Personalise with variables: the business name, city and trade are filled in for each recipient. In Prospya you start from a template (website, social media, software, coaching, supplier) or let the AI write the email from one sentence about what you sell; the preview shows the message exactly as a real business will receive it. More examples: 7 cold email templates.

Step 3: send without landing in spam

Gmail and Outlook filters judge the sender as much as the message. The basics:

• Send gradually: a few dozen, then a few hundred emails a day, never thousands at once from a new address.
• A real reply address: replies must land in your mailbox, and you must answer them.
• An unsubscribe link in every email, visible and working in one click.
• Few links, no attachment, no capitals, no "free".
• Drop addresses that bounce after the first bounce.

Prospya applies these rules for you: small batches with a daily cap, an unsubscribe link and Gmail's "unsubscribe" button added to every email, bounced or reported addresses blocked for everyone, and a campaign pauses itself if bounces go up. Details: cold email deliverability.

Step 4: track replies and follow up

Most replies come within 48 hours, then after a follow-up. A simple method:

1. Businesses you emailed move to "Contacted" in your tracker.
2. Those who reply move to "Interested", with a next action (a call, a quote).
3. No reply after 5 to 7 days: one short, polite follow-up, as a reply to the first email.

One follow-up often doubles the replies; stop after two. Combine both channels where it helps: an email first, then a short call two days later to the businesses that opened the conversation or that matter most to you. The email gives you a reason to call ("I wrote to you on Tuesday about your website"), and the call turns a silent prospect into a yes or a no. Keep everything in one place so you never email someone who already said no, and never call twice the same day. See the follow-up sequence.

Example: a complete campaign to the restaurants of Annecy

Here is what a simple campaign looks like from start to finish, for a web agency targeting restaurants:

1. The list: search "restaurants in Annecy", filter "with email". Prospya shows 168 restaurants with an address; only verified addresses go into the campaign.
2. The subject: "a question for {name}". Short, personal, no sales words.
3. The message (about 80 words):

Hello, I came across {name} while looking for a restaurant in {city}. Your reviews are great, but there is no website to see your menu or book a table. I build simple websites for restaurants in {city}, ready in a few days. Would it help if I showed you an example? Julie, Studio Web

4. Sending: spread over the day, with an unsubscribe link at the bottom of every email.
5. Follow-up: those who reply move to "Interested"; the others get a two-line follow-up a week later.

With a message like this, the salesperson's job comes down to answering the interested owners and calling them.

The mistakes that sink a campaign

• Emailing everyone: a list of "every business in France" forces a vague message. One trade and one city give a precise one.
• Talking about yourself first: "Our agency, founded in 2012, offers…" reads like an ad. Start with the business.
• Asking for too much: a 45-minute demo is a big ask from a stranger. A yes-or-no question is enough.
• Sending everything at once from a new address: filters notice. Spread it out.
• Not following up: many replies come after the follow-up, not after the first email.
• Ignoring unsubscribes: it is illegal and it hurts your sender reputation.

What the law says (France and Belgium)

In France, emailing professionals without prior consent is allowed if the message concerns their business, the sender is identified and the recipient can easily object to further messages (CNIL position). Belgium is stricter: sending without consent is in practice limited to generic company addresses (contact@, info@). In every case, honour unsubscribe requests immediately.

FAQ

How many cold emails should I send per day?

Start with 20 to 50 emails a day from a new address, then increase gradually to 100 or 200. Regular, moderate sending is better delivered than one big wave. Prospya caps sending at 200 emails per day per account.

Do I need to send from my own domain?

Not to get started: Prospya can send from a dedicated sending address, and replies land in your own mailbox. Sending from your domain (contact@yourcompany.com) is even better for deliverability and your brand; it only takes three DNS records.

Is it legal to cold email a local business?

In France, yes, if the message concerns their business, you are identified and every email lets them unsubscribe easily. In Belgium, stick to generic addresses or get prior consent. Always honour unsubscribe requests.

What reply rate can I expect?

With a targeted list (one trade, one city) and a short personalised email, reply rates of a few percent are common, and a follow-up raises them noticeably. Targeting and the first line matter more than the length of the message.

Can I email businesses that have no email address?

No, email needs an address. For businesses without one, the phone is still the best channel: the same Prospya records give the number, and you can prepare with cold calling scripts.
