Website design and development companies · Email marketing
Reach the past client before their site turns four.
Email marketing for a web company is the note that reaches a past client before their site is old, and the one that keeps an agency thinking of you for the next build. GullySales builds the list from your project records and times each send to a renewal.
Scope, fee, reporting and term are agreed in writing after we have read your brief and spoken to you.

What email marketing means
Email marketing is sending planned messages to a list of past and prospective customers who have agreed to hear from you. It suits offers, updates and staying in touch with someone who is not ready to buy yet. GullySales writes and schedules these emails and tracks who opens, clicks and enquires.

For website design and development companies
Where it usually goes wrong, and what we would do.
“Your best list is the invoice book”
Every business you have built for knows your work already, and every one of those sites ages by the month.
“Renewal dates decide the send”
A hosting renewal is the one week in the year an owner thinks about their website, so that is when the mail lands.
“Agencies want a reminder, not a newsletter”
A note carrying the two builds you just finished keeps you on an agency's list for the next one.
What we do
What we deliver for website design and development companies.
Every deliverable, what it covers for you, and the result it is there to produce. Nothing here is an extra.
A list built from your project records
Every client you have built for, with the platform, the launch year, the renewal month and who signed off, cleaned of people who have moved on.
Result: A send reaches owners rather than dead addresses.
A renewal note per client
A short mail before each hosting or domain renewal, setting out what is due, what it covers and the one thing you would improve this year.
Result: Renewals stop being an awkward invoice out of nowhere.
A platform update warning
A note to clients running a version going out of support, explaining the risk in plain words and what the update would cost.
Result: Security work is sold before a site is broken into.
A three-year note offering a refresh
A mail to every client whose site turns three, with a screenshot of how it now looks on a current phone and a price band for the work.
Result: The redesign comes to you rather than to a stranger.
A note to agency partners
Two recent builds, your current turnaround and the capacity you have free, sent to the agencies and consultants who pass work to you.
Result: You are remembered on the day their client asks.
A line when a client's competitor launches
A one-paragraph mail to an owner when a business in their trade puts up a new site, naming what it does that theirs does not.
Result: The redesign conversation starts before they notice on their own.
How the result is measured
- Open rate
- Click rate
- Enquiries from email
Recorded as a baseline before work starts, so every later report has an honest comparison.
What must be in place first
What a web company needs in place before it emails past clients about renewals and refreshes.
- A client record with the site facts
- For each site hold the domain, host, platform and version, the launch date, the renewal dates and who pays. A note about an ageing plugin or a renewal needs these facts.
- Permission from the project
- Add to the contract that the client may receive maintenance and renewal notes by email. Marketing beyond that needs a separate agreement and an opt-out.
- Renewal dates you manage honestly
- Check whether the client or you hold the domain and hosting. Never imply control you do not have. Tell the owner who is responsible for each renewal.
- A clear line on what is service and what is sales
- A security update notice is service mail. A refresh offer is a sales note. Keep them on separate lists and templates.
- A sender who built the site
- Send from the project lead or founder on your domain. A client replies to the person who knows the site.
- An opt-out and a handover record
- Honour requests to stop mail, and note whether the client has left. A client who moved to another firm must not receive your renewal note.
Who it is for
This is written for these website design and development companies.
- Small web design studios for local businesses
- WordPress and WooCommerce developers
- Shopify and e-commerce website builders
- Custom web application developers
- UI and UX design firms
- Web companies focused on one industry, such as healthcare or real estate
- Hosting and website maintenance providers
- Freelance web developers building a team
Not for
It is not the right fit if.
- Your project records have no client email addresses or renewal dates, so there is no list to write to.
- You have no refresh or maintenance offer ready, and a note to an older client would ask for nothing.
- Most past clients were supplied through an agency that owns the relationship, and mailing them directly would break the arrangement.
How it works
How the email marketing work runs
The work itself, in order. How an engagement starts, from your brief to a written scope, is set out on our method page.
- 1
Understand your list
We review who is on the list, how they got there, what they agreed to, and how long since they last heard from you.
- 2
Audit past sends
We read past campaign reports, your sending domain settings and any spam complaints to see what has and has not worked.
- 3
Segment and plan
The list is split into groups and a sending calendar is agreed, with a rule for unsubscribes and quiet addresses.
- 4
Write and set up
Emails are written, checked and scheduled in your email tool. Welcome and nurture emails are set to send on a trigger where that fits.
- 5
Measure and adjust
We read clicks, replies, enquiries and complaints by segment, and change subject lines, timing and content to match.
Where this fits
Three pieces of sales work, in this order.
This work sits inside sales process design, at stage 0, foundation. The audit comes before it, and sales management keeps it running.
Step 1
Sales audit
Find where deals are being lost and what to fix first.
Start here if you cannot say where orders are lost.
Step 2 · you are here
Sales process design
One written way to sell, from first enquiry to repeat order.
Start here if every salesperson sells differently.
Step 3
Sales management
A target, a review routine and someone who owns the number.
Start here if the team has targets and no routine.
