Buying a lead is only half the job. A qualified request landing in your inbox is worth nothing until it has been turned into a conversation, then an appointment, then a signed job. It's the follow-up — how you get back in touch, at what pace and on which channels — that decides whether the lead you paid for becomes a customer or stays a dead line in a spreadsheet. Two businesses buying exactly the same leads from the same provider can get radically different results based on their follow-up discipline alone.
This dossier brings together the concrete best practices of lead follow-up in Switzerland: how fast to call back, how many times to follow up and over what period, how to combine phone, e-mail and messaging, what to say at each contact, and how to measure the effectiveness of your follow-up to improve it. It complements our dossiers on choosing a provider, lead quality and the nLPD legal framework: once the right lead has been received by the book, everything comes down to your ability to follow it up methodically rather than at the mercy of whatever time you happen to have that day.
First-contact speed, the decisive factor
The delay between receiving a lead and your first call is the single lever that weighs most on your conversion rate. A lead has just expressed a need: their intent is at its peak the exact moment they fill in the form. A few hours later they have moved on, may already have spoken to a competitor, or no longer remember exactly what they asked for. On a shared lead, the first professional to pick up the phone starts with a considerable head start: the conversation they open often closes the door before the others have even called back.
In practice, the goal is a first contact within minutes of receiving the lead, and within the hour at worst. This doesn't require being available around the clock, but it does require a process: an immediate notification to the person responsible, an alert channel that doesn't get lost in a cluttered inbox, and a clear rule on who calls back and when. Letting leads pile up to handle "at the end of the day" is the most expensive mistake in follow-up: every hour of delay mechanically erodes the probability of reaching the customer and converting them.
Building a follow-up cadence that lasts
A single call almost never does it. Most leads don't answer on the first attempt — not from lack of interest, but because they're at work, out and about, or don't recognise the number. Giving up after one try means throwing away most of what you paid for. The best practice is a planned sequence of several attempts spread over several days: for example two attempts on day one, then a follow-up on day two, day four, day six and day nine, gradually spacing out the contacts as the sequence goes on.
This cadence must be written and systematic, not left to inspiration or the mood of the moment. Vary the call times — a customer unreachable in the morning sometimes answers late in the day — and set in advance a maximum number of attempts beyond which the lead is marked "dormant" rather than abandoned. The point is a balance: enough persistence not to lose a hesitant customer, but without tipping into harassment, which damages your image and can drive away a prospect who might have converted a few days later.
Combining channels: phone, e-mail and messaging
The phone remains the most effective channel for a hot lead: it allows a real conversation, qualifying the need live and booking an appointment on the spot. But a customer unreachable by phone is not a lost customer: many will happily reply to an e-mail or a short message while they won't pick up a call from an unknown number. The best practice is to combine channels rather than betting on just one: after an unanswered phone attempt, leave a brief voicemail and then follow with something written that reminds them who you are and why you're calling.
Each channel has its role. The phone carries the conversation and the commitment; e-mail is for sending a detail, a quote or a written summary the customer can reread at leisure; SMS or instant messaging offer short-form responsiveness and high open rates for proposing a slot or confirming an appointment. Be careful, however, to respect the consent collected and the channel the customer has authorised, in line with the nLPD, and not to multiply touchpoints to the point of saturation: the goal is to open several doors, not to overwhelm.
Getting the message right at each contact
Following up doesn't mean mechanically repeating "hello, did you get my message?" Each contact should add something new and remind the customer of the value. Lean on the detail of the form — the type of job, the location, the urgency mentioned — to show you've read their request and are addressing them, not a list. A personalised message that restates the expressed need and proposes a concrete next step stands out immediately from the generic follow-up the prospect has already received from three competitors.
Stay short and action-oriented. The aim of each message is not to sell everything, but to obtain the next micro-decision: accepting a callback, booking a slot, receiving a quote. Propose a specific date rather than a vague "whenever suits you," adopt a professional but human tone, and reserve the last message of the sequence for a door left open without pressure: saying you remain available should they want to move forward later sometimes converts prospects that persistence alone wouldn't have won over.
Tracking, measuring and improving your follow-up
You can only manage what you measure. For each lead received, record at a minimum the date received, the number of attempts, the channels used, the status and the outcome. A shared spreadsheet is enough to start; businesses handling larger volumes move to a simple CRM that automates follow-ups and reminders. The key is being able to answer, at any time, a basic question: how many leads received this week were actually contacted, in how many attempts, and with what appointment rate?
Then track a few indicators that reveal where value is being lost: average time to first contact, reachability rate, appointment rate and final conversion rate. Compare these figures across lead sources and over time to tell a request-quality problem apart from a problem in your own follow-up process. Test one change at a time — a tighter cadence, a new message, an extra channel — then measure its effect. This discipline turns follow-up from a disorganised reflex into a managed sales lever whose return improves with every cycle.
