HTML Email Templates in BigWave: What They Are and Why They Matter
Every invoice, quote, and alert BigWave sends out leaves an impression. A polished, on-brand email tells your customer you’re organized and easy to do business with. The tool that makes that polish repeatable is the HTML email template.
This is the first post in a three-part series on email templates in BigWave:
- What they are and why they matter (you’re reading it)
- HTML templates for invoice emails
- HTML templates for alerts and everything else
What is an HTML email template?
An HTML email template is a reusable layout for the emails BigWave sends on your behalf. Instead of retyping the same email every time — and risking typos or missing details — you design the layout once. From then on, every email of that type is poured into the same professional shell automatically.
The “HTML” part simply means the template is built with the same building blocks as a web page: headings, tables, colors, logos, and buttons. That’s what lets your emails look like a designed document rather than a wall of plain text.
The magic is in the field codes (also called tags). A field code is a placeholder you type into the template — something in [square brackets] — that BigWave swaps out for the real value when the email is sent. You write the template with placeholders; your customer receives it filled in with their actual name, figures, dates, and links.
Why bother?
A single well-built template pays off in several ways:
- Consistency — Every customer gets the same clean, branded layout, no matter who on your team hits send.
- Speed — There’s nothing to format at send time. Pick the template, add a personal note, and go.
- Accuracy — Because BigWave fills in the details automatically, what the customer sees always matches the record. No copy-paste mistakes.
- Professional image — Logos, brand colors, and a tidy layout make even a small operation look established.
You don’t even need to know HTML
Here’s the part that surprises people: you don’t have to write any HTML yourself. You can hand the job to an AI assistant.
Give an AI tool — ChatGPT, Claude, or whichever you prefer — your logo and the text you want in the email, and ask it to build you an HTML email template. Something as simple as:
“Create a clean, mobile-friendly HTML email template using my logo (attached) and brand colors. Include a greeting, a short message area, and a footer with my company address. Keep all styling inline.”
In seconds you get a complete, good-looking template that’s easy to tweak and ready to copy and paste into BigWave. Want the header a little bigger or the buttons a different color? Just ask the AI to adjust it, or edit the values yourself.
Then swap the sample text for field codes
When AI builds your template, it fills it with sample text — a fake name, a placeholder date, and so on. Your one job is to replace that sample text with the matching BigWave field code so the system knows what to fill in.
For example, the AI might generate a greeting like this:
<p style="font-size:16px;">Hi John Doe,</p>“John Doe” is just a sample. To make BigWave personalize it for each customer, you replace the sample name with the field code in square brackets:
<p style="font-size:16px;">Hi [AccountName],</p>Now, when a real email goes out, BigWave swaps [AccountName] for the customer’s actual name — “Hi Acme Plumbing,” “Hi Maria Lopez,” and so on. You do the same thing everywhere a real value belongs: dates, totals, addresses, links. The full list of codes for each email type is in the next two posts.
Two rules that save headaches:
- Keep all your styling inline on each element (e.g.
<td style="...">). Email apps strip out separate stylesheets, so a<style>block at the top of your template often won’t survive the trip — which is why we tell the AI to keep styling inline.- If a field code shows up as literal text in a preview — you see
[AccontName]instead of a name — it’s misspelled. Codes have to match exactly. Fix the spelling and preview again.
How to put one to work
- Get your layout. Either build it in the template editor or have AI generate it from your logo and text, then paste it in.
- Drop in field codes wherever a real value belongs, replacing the sample text the same way you replaced “John Doe” above.
- Preview against real data. Confirm every code resolves to a value. Any leftover
[bracketed]text is a typo to fix. - Save and send. From now on, sending is as simple as choosing the template and adding your personal note.
That’s the whole idea. Set the template up once and every email afterward is fast, accurate, and on-brand.
