Business Email for an Auto Repair Shop: Approvals, Fleets and Warranty Work

The most expensive sentence in a repair shop is "but you never said it would cost that". The cheapest defence is an email from the shop's own address with the estimate, the photo and the words "reply YES to approve", sent before the work starts. Add fleet customers who need a company address to open an account, parts suppliers who send invoices all day, and warranty administrators who only deal with registered businesses, and a garage has more reasons for proper email than most trades.

Quick answer

Create service@, estimates@, parts@ and invoices@ on your own domain, with name@ for the owner and the service advisor. Send every estimate and every extra-work approval from estimates@ with a photo attached and a one-line approval request. Use invoices@ for fleet accounts and warranty claims so the paperwork has one home.

The addresses to create

• service@yourshop.com for booking requests, "is my car ready?" and general customer contact. A group with the service advisor and the owner.
• estimates@yourshop.com for quotes and approvals of additional work. A group with the service advisor and the owner; every approval thread lives here.
• parts@yourshop.com for suppliers: orders, back-orders, returns and their invoices. A mailbox read by whoever orders parts, kept separate so supplier traffic never buries a customer.
• invoices@yourshop.com for customer invoices, fleet account statements and warranty claim paperwork. A mailbox read by the bookkeeper.
• name@yourshop.com for the owner and the service advisor. Technicians do not need mailboxes.

Written approvals

Diagnose, photograph, email, wait. The approval email from estimates@ has the registration number in the subject line, the fault in one sentence, the price including parts and labour, the photo, and "reply YES to approve". The reply is the record. If the customer phones instead, send a one-line "as discussed, approved by phone at 10:40, £X" so there is still a written trail. A shop that does this has very few invoice arguments and wins the ones it has.

Fleet and warranty work

Fleet managers, leasing companies and warranty administrators open accounts with businesses, and the application asks for a company email address. A gmail.com address is refused by some and quietly marked down by the rest. Use invoices@yourshop.com on the account application, send monthly statements from it, and keep claim correspondence there. Warranty claims in particular are a paper trail: the claim, the authorisation number, the parts invoice and the payment all in one mailbox you can search by registration number.

Set it up in an afternoon

1. Add your domain in OquMail and paste the MX, SPF and DKIM records at your registrar. The DNS checklist has the exact values.
2. Create service@ and the owner's name@ first, then a name@ mailbox for each person who replies to customers.
3. Create the shared addresses as groups and add the right people as members. Each member gets a copy in their own mailbox, so nothing depends on one person checking one inbox.
4. Set a signature on every mailbox in webmail with the phone number, the address and the licence or registration number where your trade requires it.
5. Put the new addresses in the Google Business Profile, on the website, on invoices and on the vehicles, in that order; the profile is where most local leads start.
6. Turn on two-factor authentication for the owner account. Invoice fraud starts with a stolen inbox.

Mistakes specific to the trade

• Approvals by phone with no follow-up email. The customer remembers a smaller number.
• Supplier invoices arriving in the same inbox as customer bookings. The customer waits, and the supplier's early-payment discount is missed.
• Letting the garage management software send invoices from a no-reply address. Fleet accounts payable teams reply to it with queries, and nobody sees them.
• Paying a supplier's "new bank details" email without a phone call. Garages are a known target for this fraud because they pay many invoices quickly. The supplier templates include the invoice-dispute wording.

Common questions

Can I send a video of the fault instead of a photo?

Yes, but not as an attachment; a 30-second phone video is often over 50 MB and will bounce. Upload it to a shared drive or an unlisted video link and put the link in the approval email, with a still photo attached so the email itself still shows the problem.

What goes on the invoice?

invoices@yourshop.com for payment questions and service@yourshop.com for bookings. The website, invoice and business card guide explains why those two and no others.

Do MOT or inspection reminders belong in email?

Yes, from service@, a month before the date, with a one-click reply to book. It is the most reliable repeat business a shop has, and it costs nothing when the mailbox is free.
