Software development companies · Email marketing
Propose phase two before the client goes shopping.
Email for a software firm is how a finished project turns into support, a next phase or a referral, and how a lost proposal comes back a year later. GullySales builds the list from your delivery records and times each send.
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.

Sales and marketing for software development companies, the overview.
Last updated 5 Oct 2026.
For software development companies
Where it usually goes wrong, and what we would do.
“A launched project ends the conversation”
Nobody proposes what comes next, so the client finds another vendor for support six months later.
“Lost proposals were usually lost to timing”
The budget moved to the next year, and nobody wrote again when that year arrived.
“IT heads keep mail, founders keep WhatsApp”
An established company wants the document in email for its approval file, and a startup founder answers on the phone.
What we do
What we deliver for software 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 delivery records
Every client, their systems, the launch date, the support status and the person who signed, cleaned of people who have left.
Result: Each send reaches somebody who used the work.
A next-phase note after every launch
A short mail a month after go-live with what the data shows, what is worth adding next and what it would cost.
Result: Phase two is proposed before a competitor appears.
A support offer in writing before warranty ends
What is covered, the response times and the annual price, sent before the warranty period closes rather than after a breakage.
Result: Support becomes an agreement, not a favour.
A note on ageing systems and versions
A mail to clients running a framework, library or platform going out of support, with the risk and the work involved.
Result: Upgrade work is sold before a security problem.
A revival sequence for lost proposals
Two mails to buyers who went quiet, the first with something useful in their domain, the second timed to their budget month.
Result: Last year's no becomes this year's discovery.
Replies and opportunities counted by list
What each send produced, measured as replies and opportunities rather than opens, against the baseline.
Result: The list that never answers gets rested.
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 software firm needs in place before it writes to past clients and lost proposals.
- Delivery records as the source
- Build the list from signed projects, with the client contact, the stack, the launch date and the end of warranty. Anyone not in that record needs a separate reason to be mailed.
- Contract terms checked for what you may say
- Read the NDA and the contract before naming a client or a product in any mail. If it forbids it, describe the work in general terms.
- A list split by stage
- Keep live clients, finished projects, lost proposals and referral partners apart. A client mid-delivery should not receive a win-back note.
- A sender who is the person they worked with
- Send from the account lead or founder they dealt with, on your domain, with SPF and DKIM set. A reply goes to someone who remembers the project.
- Overseas clients' rules known
- If you mail clients in Europe or elsewhere, check what their local law expects about consent and opt-out for business mail, and record the basis for each contact.
- An unsubscribe and a correction route
- Let a contact opt out or tell you they have left the company. People move jobs, and a stale record sends the mail to a stranger.
Who it is for
This is written for these software development companies.
- Custom software development companies
- Mobile app developers for Android and iOS
- Product engineering firms working with startups
- IT consultants and technology advisers
- SaaS product companies selling to Indian businesses
- Offshore development centres serving overseas clients
- Firms specialising in one domain, such as healthcare, logistics or fintech
- Low-code and automation developers
- Software firms bidding for government work on GeM
Not for
It is not the right fit if.
- You have no record of past clients' consent to be written to, so the first mail would be unwelcome.
- Contracts forbid you from naming clients, and you have not checked what a mail may say.
- No one owns the list, and the contact at each client has changed without anyone knowing.
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.
