A self-employed trainer has just connected a signup form to her newsletter, but behind that form there's nothing: a technical confirmation email, then silence until the next monthly newsletter, sent to everyone without distinction. People who just signed up receive the same message as those who've been subscribed for two years, at the same pace, with no message accounting for when they actually joined the list.
An email sequence answers a question that simply sending a newsletter never asks: what does this person need to know or do, at this exact moment in their relationship with you? Building a sequence means deciding on a role for each message, rather than stacking up sends.
This article details the method for designing a sequence suited to context, the French rules governing consent and the right to object, and how to define a sequence exit so no one keeps receiving a message that no longer concerns them.

A sequence connects moments, not isolated sends
A standalone email is judged on its own content: subject line, body, call to action. A sequence is judged differently, on how the messages chain together and on what each one assumes the recipient already knows. Ignoring that difference produces sequences that repeat the same information three times, or that, conversely, assume knowledge the recipient never actually received.
What the recipient already knows before each message
Before writing a message, you need to establish what the person already knows at this exact stage of the journey — have they already received the promised document, have they already visited the offer page, have they already asked a question that went unanswered. A message that repeats information already delivered wears down the recipient's patience; one that assumes information never delivered creates confusion that can cost the entire relationship.
The expected action after each message
Every email in a sequence should aim at a precise action, even a modest one: opening a document, answering a question, visiting a page. A message aimed at no identifiable action — a plain reminder of existence — rarely weighs on the recipient's decision and deserves to be questioned before it's scheduled: does it actually serve the recipient, or only the sending frequency the sender wants to maintain?
Consent and unsubscribing: what the law requires
French law precisely governs commercial email prospecting, with different rules depending on whether the recipient is an individual or a professional — a distinction to know before scheduling the smallest sequence.
Prior consent, the principle and its exception
Article L34-5 of the French Postal and Electronic Communications Code requires prior, free, specific and informed consent before any prospecting email is sent to an individual. The CNIL specifies a "soft opt-in" exception: someone who is already a customer can receive, without renewed consent, messages about products or services similar to what they already bought — provided they were informed of this and can easily object from the point of collection and in every message. For a professional recipient contacted in the context of their activity, prior consent isn't systematically required, provided the person knows the source of their contact details and can easily object to future messages.
The unsubscribe link, mandatory in every message
Every prospecting message, without exception, must offer a simple way to object to future messages — in practice, a functional and visible unsubscribe link, not a generic contact email that would have to be requested manually. A sequence built with an automation tool must confirm that this link works at every step, including automatically generated messages, and that unsubscribing mid-sequence actually stops the following messages rather than letting already-scheduled messages go out regardless.
Designing a sequence in five steps
A sequence designed without a method often looks like three emails written on the same day, with no real connection between them. The five steps below structure the design around the recipient's actual journey rather than the sender's calendar.
Step 1: Choose the sequence type suited to the context. A welcome sequence, a prospecting sequence and a follow-up sequence after a specific event share neither the same tone nor the same pace; starting with the wrong type often means redoing everything midway through.
Step 2: Define what the recipient knows before the first message. Note precisely the event that triggers the sequence — signup, download, an unanswered question — since it determines what the first message can safely assume is already known.
Step 3: Assign a single function to each message. One message answers a common question, another addresses an objection, a third proposes a conversation: keeping a single message from trying to do everything at once clarifies what the recipient should take away from it.
Step 4: Set timing based on observed behavior, not a default template. A sequence template proposes indicative delays; adjusting them to the audience's reality — typical decision time, how often previous messages were opened — makes the sequence more relevant than an identical schedule for every context.
Step 5: Define the sequence exit before activating it. Specify the action that should stop the following messages — a booking made, a reply received, an unsubscribe — so no message that has become unnecessary, or even irritating, goes out after its purpose has already been achieved.
| Sequence type | Trigger | Main function | Typical exit condition |
|---|---|---|---|
| Welcome | Signup to a list or a service | Introduce the offer and build initial trust | First meaningful action taken |
| Prospecting | Identified contact with no prior purchase | Demonstrate value before proposing a conversation | Meeting booked or explicit refusal expressed |
| Follow-up after an event | Document downloaded, question asked, quote sent | Answer likely questions and re-prompt the action | Action taken or new direct contact established |
The three sequence types most useful to a self-employed professional
Three sequence types cover most of the needs of a self-employed professional or a small team, without automating beyond what's genuinely useful.
Welcome and prospecting
The welcome sequence turns a signup into an ongoing relationship: it introduces the offer, answers the most common questions and establishes an initial level of trust before any direct commercial ask. The prospecting sequence, meanwhile, targets an identified contact who isn't yet a customer: it demonstrates the offer's value through concrete proof before proposing a conversation, rather than asking for a sale in the very first message.
Follow-up after a specific event
The follow-up sequence responds to an identifiable event — a document downloaded with no further action, a question left unanswered, a quote sent with no response. It differs from the previous two by having a one-off rather than a continuous trigger, and by a shorter window of relevance: following up on a six-month-old quote doesn't carry the same meaning as following up a week after it was sent.
When an automated sequence isn't enough
A well-designed sequence schedules messages, but it doesn't replace human judgment at certain precise moments. If someone replies directly to a message in the sequence, that reply must leave the automated path and receive a personal response, or the recipient gets an automatic message in reply to a real question — an experience that damages the relationship more than plain silence would have. A sequence also doesn't compensate for a list built without valid consent: no adjustment to timing or content makes a send compliant if it's based on collection that doesn't comply with Article L34-5. Finally, a sequence's performance — open rate, click rate, unsubscribes — is observed in the sending tool itself, never in the copy prepared beforehand, which cannot predict those results.
What we observe among self-employed professionals building their first sequence
In the conversations we have with self-employed professionals about their emails, the difficulty is almost never technical — most email tools offer automated sequences in a few clicks. What holds people up is knowing what to say at each step without repeating themselves, and defining a clear exit so as not to keep chasing someone who already replied through another channel. A well-built sequence doesn't replace the relationship; it organizes when each message arrives, so the relationship has time to settle before any direct ask.
Training to make your email sequences more reliable
Knowing the consent rules in theory doesn't stop a misconfigured sequence from breaking them in practice, particularly when an unsubscribe isn't properly propagated to an automation tool. According to the OPIIEC study of June 2025, 64% of French companies already use AI solutions and 88% expect to adopt them within three years; productivity gains observed after AI training in SMEs sit, as an order of magnitude, between 15 and 25%, a benchmark to read as a trend rather than a guaranteed result.
Frequently asked questions
Can an email sequence be sent without the recipient's prior consent?
For an individual, no, except under the "soft opt-in" exception: someone who is already a customer can receive messages about similar products without renewed consent, provided they were informed and can easily object. For a professional contacted in the context of their activity, prior consent isn't systematically required, but the person must know the source of their contact details and be able to easily object to future messages, from the very first one. When in doubt about a contact's real status or where their address came from, the safer choice is to ask for explicit consent before sending anything, rather than assuming an exception that might not apply.
How many emails should a sequence contain?
There is no universal number: it depends on the function each message must fulfill, not on a standard template to reproduce systematically. A welcome sequence can be limited to two or three messages if the offer is simple, while a prospecting sequence over a long decision cycle can legitimately include more. Adding a message with no identifiable function dilutes the sequence rather than strengthening it.
What should happen if someone unsubscribes mid-sequence?
The unsubscribe must immediately stop every following message in the sequence, including ones already scheduled in the automation tool; this is a requirement, not a configuration option. Check that the tool in use correctly propagates an unsubscribe to every active sequence the person appears in, not just the one they unsubscribed from, to avoid another automated journey continuing to write to them. A regular test — sign up, unsubscribe, then confirm no further message arrives — remains the most reliable way to confirm that propagation actually works, rather than assuming it does because the tool claims it.
What is the difference between an email sequence and an ad campaign toward a landing page?
An email sequence targets people already identified, whose address was collected with consent or a prior relationship, and unfolds over days or weeks. An ad campaign toward a landing page targets strangers who have no relationship with the sender yet, and plays out in a single click toward a page that must be audited separately. The two often work together: the landing page captures the address, the sequence then takes over to build the relationship over time. Confusing the two means treating someone who just filled out a form as if they already had an established relationship, a tone that rarely fits a sequence designed for existing customers.
Building an email sequence rests on three decisions that don't change from one context to the next: assigning a precise function to each message, respecting the consent and right to object required by French law, and defining a clear exit before activation. That is exactly what Market Emails sequence writing structures automatically, message by message, never sending anything on its user's behalf.
