Email marketing for UK tradespeople: quotes, reminders and deliverability

What to take away

Build the quote follow-up sequence first

Email marketing for plumbers and electricians is mostly follow-up. Most jobs are lost to silence rather than price, and a quote is a lead with a shelf life.

Stop the sequence on a reply, a booking or a clear no. Messages that keep arriving after a refusal push customers to mark you as spam.

Message types and the timing that suits trade work

Quote follow-up emails in the UK land better in the same afternoon than on a Friday. Length matters less than arriving while the customer is still deciding.

Photos, attachments and site-based sending

Photos win trade work, but a 20MB email with eight images invites filtering. Host the quote in Drive or your job software and link to it instead. Compress photos before sending and use one image per email. Gmail rejects attachments over 25MB.

Many trades send between jobs, from a phone, on 4G. That produces bursts of near-identical messages from a mobile connection. Schedule the quote to leave within the hour instead of sending live from the driveway.

Send every quote before you leave the postcode. Delay is how the job goes to someone else.

Consent, the soft opt-in and sole traders

PECR covers electronic marketing to UK subscribers, and sole traders and partnerships count as individual subscribers. Cold email to them needs consent. Limited companies fall outside that rule.

Existing customers sit under the soft opt-in. You may email similar offers if you offered an opt-out at the point of sale and in every message. Record the date and source of each consent, and check the ICO direct marketing guidance when a campaign changes audience.

Authentication for a trade domain

Send from your own domain, such as smithplumbing.co.uk, rather than a free mailbox. Add an SPF record listing every service that sends for you, so receiving servers know which addresses may send for your domain. Sign with DKIM so each message carries a verifiable signature.

DMARC ties the two together. Start at p=none to collect reports, and move to quarantine once they look clean. Trade email deliverability also tracks complaint rates, bounce rates and steady volume. If open rates fall across every message, our page on choosing a deliverability consultant in London sets out audit scope and the questions that expose resellers.

Example: the annual boiler service reminder

Take a customer whose boiler was serviced in March. Email reminders for service businesses should start ten months later, in January. Run this checklist before the sequence goes live.

Booked customers re-enter the sequence the following year, which turns one job into recurring work.

Software, support and where to read next

Trigger depth decides whether a platform can run a twelve-day quote sequence. Ask how many steps and conditions it supports, and whether a reply stops the flow. Our guide to email automation for UK small business covers pounds-based pricing lines, UK support hours and accounting links such as Xero and QuickBooks.

If you also serve walk-in customers from a showroom, a unit or a cafe, the booking and seasonal timing advice in email marketing software for restaurants applies just as well.

Common questions

How many quote follow-up emails should I send?

Three over twelve days suits most domestic work. Stop on any reply, booking or refusal.

Do I need consent to email a sole trader?

Yes. PECR treats sole traders and partnerships as individuals, so cold email needs consent unless the soft opt-in applies.

Can I attach a quote as a PDF?

It works for small files. Gmail rejects attachments over 25MB, and heavy emails are filtered more often than links to a hosted quote.

Should I send from my own domain?

Use your own domain with SPF, DKIM and DMARC. Free mailboxes limit authentication and reputation control.
