It can — or it can be a missed opportunity sitting at the bottom of every email you send. A signature with a clickable phone number, a link to book or get a quote, and your service area turns routine correspondence into a quiet, ongoing marketing channel.
Every email a business sends — invoices, follow-ups, quotes, general correspondence — ends with a signature, and most signatures are an afterthought: a name, maybe a logo, maybe a phone number that isn't clickable. For a business that sends dozens or hundreds of emails, that's dozens or hundreds of missed small opportunities to make it easier for the recipient to take the next step.
A signature that works includes: a clickable phone number (so a recipient on mobile can tap to call directly), a link to whatever the most useful next action is — booking a time, requesting a quote, or visiting the website — and, where relevant, the service area or specialty, which helps when an email gets forwarded to someone else who might need the service.
This costs nothing to fix and takes effect immediately across every future email. It's a small piece of the overall digital foundation, but it's representative of a pattern — small, free, overlooked touchpoints that collectively shape how easy or hard it is for a customer to take action.

Less critical, but still worth fixing since it costs nothing — and any email correspondence (invoices, confirmations) still benefits.
