ChatGPT or Claude will draft a good-looking email in seconds. Making it work in Outlook, speak your provider's variable format, match the rest of your emails and stay up to date is where the hours go. TemplatePort fills that gap.
From idea to an email your app sends
Draft
Copy, structure, a first design
Render everywhere
Outlook, Gmail, mobile, images off
Provider format
Each provider's variable syntax
Push and sync
Create once, update in place
Send from code
IDs and variables wired up
The difference
None of the do-it-yourself steps are hard on their own. Together, for every transactional email you need, they add up.
What a chat window can't do
Nested tables, inline styles and Outlook fallbacks for photo headers. Columns stack on phones, text stays readable with images off.
Write {{user_name}} once. We convert it for each provider, avoid Resend's reserved names, and push with the right API calls.
Your logo, colors, fonts, footer, terms and privacy links and social icons applied to every template, so welcome, receipt and reset emails look like one product.
Changed your brand color? Templates that are out of date get a badge, and Re-push all updates them in your provider in one go.
A built-in health check flags Gmail clipping, spam-like wording, missing alt text, broken links and low contrast.
Copy-ready send code for Node.js, Next.js, Python and Supabase Edge Functions, with the template IDs and variable names already filled in. Sending from Google Workspace? Paste it into Gmail as a template, or send it with Nodemailer.
Connect TemplatePort to Lovable and ask for your emails in chat, or paste one prompt that updates several at once, including emails in your own edge functions. When your brand changes, we tell you what to re-apply.
AI writes new emails in your brand's language, or translates one and keeps a copy per language. The email is marked with the right language for screen readers and spam filters.
Search free Unsplash photos or upload your own. Photo headers get an Outlook fallback and a background color for when images are off.
One template, every format
Each provider names variables differently, and getting one wrong means an email that says "Hi {{{USER_NAME}}}" to a customer. TemplatePort converts them for you on every push.
| You write | Resend | PPostmark | SendGrid | Brevo | Supabase Auth |
|---|---|---|---|---|---|
| {{user_name}} | {{{USER_NAME}}} | {{user_name}} | {{user_name}} | {{ params.user_name }} | {{ .Data.full_name }} |
| {{reset_url}} | {{{RESET_URL}}} | {{reset_url}} | {{reset_url}} | {{ params.reset_url }} | {{ .ConfirmationURL }} |
| {{email}} | {{{EMAIL_VALUE}}} | {{email}} | {{email}} | {{ params.email }} | {{ .Email }} |
Resend reserves names like EMAIL, so we rename those safely, and the send code we give you uses the same names.
Transactional emails are mostly set up once, so the Launch Pack is a single payment of €29. Generating and previewing is free.
