SaaS and web app development
We design, build and launch SaaS products, from the first screen to paying customers. Our flagship is FlyReplies, a cold email and email marketing platform we built from scratch and run every day. The same team can build yours.
Most agencies build websites. We also build the software behind them. Every product on this page was designed, coded, launched and maintained by Design Fly 24, so you work with people who know what it takes to run a real product, not just ship a prototype.
Multi user apps with accounts, workspaces, roles, onboarding and billing, built to grow.
Sending, tracking, deliverability, automations and reporting. The core of FlyReplies.
Writing assistants, reply classification, scoring and reports that save your users real time.
Plans, trials, coupons, invoices and a customer billing portal connected from day one.
A super admin area to manage users, plans, security and alerts without touching code.
Custom WordPress plugins and Elementor widgets when your product lives inside a website.
FlyReplies is our own SaaS, live at flyreplies.com. It replaces separate tools for lead finding, cold email, newsletters and automations with one app. We use it every day to win clients for Design Fly 24, which is why every feature is shaped by real use.
Here is a tour of the product, using sample data.
A welcome tour, a setup checklist and a short guide on every page, so new users know exactly what to do next.
Write a sequence, then let AI rewrite a step in different styles and send each version to a share of your leads.
Reply rates per writing style across every campaign, so the winner is obvious.
Replies from all mailboxes land in one place, labelled by AI as interested, meeting, question or not now.
A visual builder with emails, waits, yes or no checks and tags, triggered by forms, lists or segments.
Pop ups, slide ins and inline forms with a live device preview, plus a free WordPress plugin.
Sent, replies, positive replies, meetings and bounces, broken down by campaign and mailbox.
Good replies become deals on a simple board with value and stages.
The screens are the easy part. Most of the work in an email product is in the parts users never see.
Mailbox warmup, rotation with safe daily limits, bounce detection and automatic pausing when a mailbox struggles.
Connect Amazon SES, Brevo, SendGrid, Mailgun, Postmark or Resend to send newsletters to thousands per hour.
Open and click tracking that ignores scanners and machine opens, plus one click unsubscribe.
Two factor sign in, bot protection on login and signup, and alerts for new accounts.
Stripe plans, trials, coupons and automatic invoice emails.
Agencies can use their own logo, colors and domain and run client workspaces.
FlyReplies is the flagship, but it is not the only product we have shipped.
