Your past customers are your best ally
You don't have to ask for email addresses. A short intake form collects them with each request, and small, targeted sends tend to convert better.

This is not remarketing. It is staying in touch — no matter who you are or what you do. Systems work better than no systems, and the system here is simple: capture the address when the customer is already giving you information, then let the list grow on its own.
Quick answer
What does it take to reach every customer you've ever served in one send? An email address collected without asking, a system that captures it at intake, and one Broadcast on Pro. That is the whole game.
People won't fill out long forms
It is genuinely annoying to ask someone for their email address, which is exactly why most operators never build the list. The problem is not the ask — it is that the ask feels separate from the work.
TurboTax never asks for your email up front. It plays twenty questions, one at a time, like a conversation, and you hand over information without noticing. Not malicious — just human nature. A long garbage form goes unfilled. A conversation gets finished. A low-friction intake form works the same way: name, a couple of details, maybe a photo. The email comes along for the ride.
Cash customers don't care about a pay link
If someone is paying cash, they do not care about a pay link. The customers who matter are the ones paying by card — and that is exactly who the intake form should be quietly collecting for. You can text a pay link from your phone, but email works too, and most customers are fine entering their address to receive it. That address doubles as your broadcast list without ever feeling like you asked for it.
What a list actually buys you
Imagine a thousand people you have done work for. One promotion or sale, one Broadcast on Pro, sent. You would be surprised at the level of insight and the traction you could gain — but it takes time and consistency to build, which is where a system that captures dynamically earns its keep.
MailerLite analyzed more than 300 million emails from over 300,000 promotional campaigns and found an average conversion rate of 0.32%. Smaller, targeted sends did much better: campaigns sent to 1 to 500 recipients converted at 3.28%, while sends to 10,000 or more converted at 0.05%. MailerLite ties that gap to targeting. That dataset is ecommerce orders from opted-in store subscribers, not service bookings, so treat it as a direction, not a forecast. A short list of people who already hired you is the kind of small, targeted send those numbers favor.
Relationships are the moat
People look for the loyal one. In a world where anyone can copy a feature, nobody can copy a relationship you already have. Build the list slowly and consistently, and let the system capture it dynamically so it does not depend on your memory between jobs.
When broadcasting is the right tool
Broadcasts are a Pro feature: up to 1,500 emails a month to your own customers. They are not something to start on day one. If you are just starting out, emailing people immediately may not be the right tool for the job. It takes time to build the list and the relationships first. When you are ready, see pricing for what each plan includes.
No card to create it. A card is required 3 days later, or the workspace locks until you pick a plan.
FAQ
Do customers mind giving an email at intake?
Not when it is part of getting something done. A short form that asks a couple of questions feels like a conversation, not a chore. The email comes along for the ride.
Which plan do I need before I can email the list?
You can collect addresses on Fundamentals, Essentials, or Pro. Those plans cap customers at 150, 500, and unlimited. Email broadcasts start on Pro, at 1,500 emails a month to your own customers.
When does a broadcast list become worth real money?
When one send reaches people who already trust you. In MailerLite's ecommerce data, campaigns sent to 1 to 500 recipients converted at 3.28%, versus 0.05% for sends to 10,000 or more. MailerLite ties that gap to targeting.
How do I avoid looking like I'm spamming people I worked for?
Send rarely, send something useful, and make it easy to opt out. A promotion once a season beats a newsletter every week.
