How many emails should a lead nurture sequence have?

Short answer: Four to six emails over about 14 to 21 days suits most Australian service enquiries. Go shorter, two or three emails over a week, for low value quick decisions. Go longer, with a phone call in the mix, for high ticket work or B2B sales. Whatever the length, the sequence must stop the moment the person books, replies or unsubscribes, because that exit rule matters more than the number of emails.

Ask ten small business owners about their follow up and you will hear two answers. One is a single “just checking in” email, sent a week late if at all. The other is a twelve part drip a tool suggested, which keeps writing long after the person has decided. Neither was designed by anyone.

This article gives you a length for each type of sale, a job for every email, and the stop rules. It sits inside our guide to marketing automation for Australian small business, which covers platform choice and the full legal picture.

Why one follow up is not a sequence, and twelve is not either

One follow up fails because people rarely decide on the first nudge. Someone asks for a quote, gets busy, compares two other businesses and forgets you. A single email lands in that gap or it does not. That is a coin toss, not a process.

Twelve emails fail the other way. By the fifth, the message is about your calendar, not their job. People unsubscribe, mark you as spam, or quietly file you as the business that would not leave them alone.

Here is the view this article rests on: the number of emails is the least important choice you make. The exit rules and the job each email does matter far more. A tidy five email sequence that stops the instant someone books will beat a twelve email drip, and it protects your sender reputation as well.

Match the length to how long the decision takes

The right length follows the buying decision, not a template. A person booking an A$90 service decides in a day. A couple planning an A$25,000 bathroom decides over weeks, with a partner, a bank and two other tradies involved. Cover the window in which the decision is made, then end.

These are rules of thumb from practice, not benchmarks. Adjust them against your own booking data.

Type of sale	Emails	Spread over	Notes
Low value, quick decision	2 to 3	3 to 7 days	First email within minutes
Typical service enquiry	4 to 6	14 to 21 days	The default for most small businesses
Quoted project (renovation, landscaping)	5 to 6	21 to 28 days	Add one phone call around day four
High ticket or B2B	6 to 8	6 to 8 weeks	Calls carry as much weight as emails

The count rises far more slowly than the price. Something ten times as expensive does not need ten times the emails. It needs a phone call and more patience. The gaps should widen too: close together while the enquiry is fresh, then spread out so you read as available rather than pushy. If unsure, start with the second row and lengthen it only if it works.

Give every email one job

A sequence is not one message sent five times with the volume turned up. Each email does one thing, and you should be able to say what in a short sentence. If you cannot, delete it. A pattern that fits most service businesses:

1. Confirm and set expectations. Repeat what they asked about and say what happens next and when.
2. Answer their next question. What is included, how long it takes, what the process looks like.
3. Show something real. Photos of similar finished work or a relevant page on your site.
4. Deal with the hesitation. Usually price, timing or trust. Name it and offer a smaller first step.
5. Offer a human conversation. A direct invitation to book a call, with a link that works.
6. Close the loop. A short, polite note saying you will stop writing and the door stays open.

Notice what is missing: the email that says “just checking in” and adds nothing. Every message should give the person a fact, a picture, an answer or an easy next step. If it only asks, it is a nag. Our explainer on what marketing automation is covers how these steps get triggered once the timing is set.

A worked example: a Newcastle bathroom renovator after a quote

This is a hypothetical, built to show the shape of a sequence. The figures are invented and are not a benchmark.

A Newcastle renovator sends a quote for an A$22,000 bathroom. The sequence starts the moment the quote goes out and runs 21 days.

Day	Email	Its one job
0	Quote received	Summarise the scope in three lines, say when the owner will call
2	What happens after you say yes	Explain timeline, deposit and start date
6	A similar job	Photos of a comparable finished bathroom
11	If the price is a stretch	Offer a scope change, and say what changes and what does not
17	Last check in	Say you will stop writing, offer a 15 minute call, state until when the quote stands

The gaps are 2, 4, 5 and 6 days, which add up to 17 days for the five emails, and the window closes on day 21. The owner also phones on day four, because at this price a call does more than another email would. Every email stops if the customer replies, books or unsubscribes.

When to stop, and the mistake that burns leads

The costliest mistake in email automation is following up someone who has already booked. A customer pays a deposit on Tuesday, then on Thursday receives “Have you had a chance to look at our quote?” It tells them your systems do not talk to each other, at the moment you should be building trust.

Set four exit conditions before writing any email:

• Booked. The moment a job, appointment or deposit is recorded, the sequence ends.
• Replied. Any reply, even “not yet”, moves them to a human conversation.
• Bought. A purchase by phone or in person counts. This is the exit people forget.
• Unsubscribed. Immediate, permanent, and honoured across every list you run.

Most mainstream automation platforms let you end a workflow when a condition is met, such as a booking, a reply or a purchase, so this is usually a setting rather than a project. Confirm yours does before you commit, and see our platform comparison for how the main options differ. The catch is that the booked and bought exits only work if the booking is recorded where the platform can see it. If bookings live in a paper diary, the platform will keep emailing. Connect them, or have the owner mark the lead as won by hand. Then test: enquire with a spare address, book yourself, and confirm the emails stop.

The Spam Act, applied to a sequence

Most emails in a sequence are commercial electronic messages, so the Spam Act 2003 applies to them, and it is safest to treat every one that way. Our pillar guide sets out the full obligation. Only the sequence-specific points follow:

• Stay on the subject of the enquiry. Consent from a bathroom quote request does not automatically cover unrelated promotions. Check the current ACMA guidance on how far inferred consent goes.
• Identify the sender clearly in every email.
• Include a working unsubscribe, honoured within five working days.
• Never use a bought list. A sequence cannot repair missing consent.

Send in their time, not yours

Australia is not one time zone. New South Wales, Victoria, South Australia, Tasmania and the ACT observe daylight saving. Queensland, the Northern Territory and Western Australia do not. A Sydney business emailing Brisbane in summer is an hour out, and Perth is further again. If your platform sends in your local time, an 8am email can land in Perth at 5am or 6am.

Public holidays differ as well. Melbourne Cup Day is a public holiday in much of Victoria and an ordinary Tuesday in Brisbane. Most platforms can send in the recipient’s time zone or pause on a holiday calendar, so use those settings if you serve several states.

Make it look like it came from a person

A nurture email works best when it reads like a note from the owner, not a campaign:

• Send from a real person’s first name and your business name, not “info” or “noreply”.
• Use a reply address someone monitors. Otherwise you have built a trap.
• Write in plain or near plain text, with one link and no banner graphics.
• Keep subject lines short and specific: “Your bathroom quote” beats a slogan.

Technically, authenticate your domain with SPF, DKIM and DMARC. It is good practice for any business email. Gmail and Yahoo tightened their bulk-sender rules in 2024 and requirements keep moving, so check their current guidelines rather than relying on this article.

Judge it on replies and bookings, not opens

Open rates are no longer trustworthy. Apple Mail Privacy Protection, introduced with iOS 15, can load emails in the background, which registers an open when nobody looked. If much of your list reads on an iPhone, your open rate is inflated.

Measure outcomes that cannot be faked: replies to the sequence, bookings and accepted quotes that follow it, and unsubscribes or spam complaints, which tell you the tone or length is off. The simple test is booked enquiries per hundred leads, before and after the sequence. To rank leads by likelihood to buy, see our guide to AI lead scoring. To check the spend is worth it first, do the break-even sum.

What to do with the leads who never answer

Some people reach the end and say nothing. Usually the timing was wrong, not the lead. You have two honest options. If they gave consent covering ongoing messages, for example by ticking a box for occasional updates, move them to a low frequency list: one useful email a quarter. If the only consent you hold is for the specific enquiry, stop. Sending a newsletter to someone who asked for one quote is a stretch of that consent, so check the current ACMA wording first. A polite stop is not a loss. Someone treated well at the end is far likelier to return in six months than someone chased until they blocked you.

This week’s one job

Take the last quote you sent that has gone quiet and write down the email jobs from the worked example for that customer. Build one sequence in the tool you already have, switch on the four exit conditions, and test it against a spare address before it touches a real lead.

Frequently asked questions

How many emails should a lead nurture sequence have?

Four to six emails over about 14 to 21 days suits most Australian service enquiries. Low value, quick decisions need only two or three over a week. High value projects and B2B sales need more emails spread over longer, plus a phone call. Whatever the length, the sequence must stop the moment the person books, replies or unsubscribes.

When should a nurture sequence stop?

It should stop the instant the person books, replies, buys or unsubscribes, and after the last scheduled email if none of those happen. Most sequences that damage a business do so by continuing after a booking, because the exit rule was never set up. Test the exit by enquiring yourself and confirming the emails stop.

Do Australian businesses need consent to send nurture emails?

Yes. The Spam Act 2003 requires consent before a commercial electronic message is sent, clear identification of the sender and a working unsubscribe that is honoured within five working days. An enquiry can support inferred consent for messages about that enquiry, but check the current ACMA guidance for how far that stretches, and never send to a bought list.

What is the best time to send follow up emails in Australia?

Send in the recipient’s local time, usually weekday mornings or early evening for consumers and business hours for B2B. Australia spans several time zones, daylight saving applies in some states and not others, and public holidays differ by state. Test two send windows over a month and keep whichever produces more replies and bookings.

How do I measure whether a nurture sequence works?

Count replies and bookings that follow the sequence, not opens. Apple Mail Privacy Protection, introduced with iOS 15, can register an open when nobody read the email, so open rates overstate interest. Compare booked enquiries per hundred leads before and after the sequence, and check unsubscribe and complaint rates alongside.
