SendGrid Email Template Builder

Design in Temway, send from SendGrid

Temway is a visual email template builder that connects directly to SendGrid. Compose a responsive email with drag-and-drop blocks, then push it into your SendGrid account as a dynamic template — ready to wire into your transactional sends or marketing campaigns via the SendGrid API.

If you’ve been searching for a “SendGrid template builder” that gives you production-grade responsive HTML without hand-authoring markup, this is it. You design; SendGrid keeps doing what it’s good at — routing, delivery, and high-volume transactional send.

Why design in a separate builder?

SendGrid’s built-in editor is functional but minimal, and most teams sending at volume author templates in code. Hand-writing SendGrid-ready HTML is where the friction lives:

• Responsive columns that drift in Outlook — hand-coded layouts are fragile; a single mistake breaks rendering in Outlook.
• Dynamic templates need Handlebars logic — pasting {{ first_name }} substitution tags by hand is easy to forget or mistype.
• No single source of truth — every transactional email (welcome, reset, receipt) is authored separately, so brand consistency drifts.
• Dark-mode rendering you can’t fully control — logos invert, transparent PNGs get dark halos, brand colors shift.

Every email Temway exports is built to render correctly across Gmail, Outlook, and Apple Mail, with responsive behavior already handled. You compose visually; the output is clean HTML that drops straight into a SendGrid dynamic template.

This isn’t about replacing SendGrid — it’s about giving your team a faster, more reliable way to design the transactional and marketing emails SendGrid sends.

How the SendGrid integration works

Connect your SendGrid account once from your Temway workspace’s integration settings using an SG.-prefixed API key. When your email is ready, choose Push to SendGrid. Temway renders the final, inbox-ready HTML and creates a new dynamic template in your SendGrid account.

• Lands as a dynamic template with your HTML attached as the first active version — ready to reference by template ID from your application code or marketing campaign.
• Two-step push mirrors SendGrid’s own model: Temway creates the template shell, then attaches the HTML as a version (the way SendGrid’s API expects).
• Authenticates with a SendGrid bearer key (SG.xxxx) scoped to template access.
• Client-safe output means the pushed HTML renders consistently across Gmail, Outlook, Apple Mail, and the rest.
• Credentials encrypted at rest — your API key is never displayed again after you connect.

SendGrid-specific details that just work

Because Temway pushes raw HTML into a SendGrid dynamic template and SendGrid processes its own tags at send time, a few things work exactly the way SendGrid users expect:

• Handlebars substitutions pass through. Paste {{ first_name }}, {{ order.total }}, {{#each items}}…{{/each}}, or any SendGrid Handlebars syntax into a Temway text block — it renders into the HTML untouched and resolves normally when SendGrid sends.
• Versioned by default. Your first push lands as “Version 1, active.” Re-push from Temway and you can manage versions inside SendGrid — useful for iterating without losing the previous design.
• Design-only by design. Temway never touches your contacts, sender authentication, suppression list, or send configuration. Those stay entirely in SendGrid — Temway only creates the template; your application decides when to fire it.

Start from a SendGrid-ready template

Don’t begin from a blank canvas. Browse the template gallery for responsive, transactional-friendly starting points — then customize the branding, copy, and layout in Temway before pushing to your SendGrid account.

Frequently asked questions

Dynamic or legacy template? Dynamic. Temway creates a dynamic template (generation: dynamic), which is SendGrid’s current recommendation and the only type that supports Handlebars substitutions. Legacy templates are deprecated by SendGrid.

Do SendGrid Handlebars substitutions and conditionals work? Yes. Anything you type into a Temway text block — {{ first_name }}, {{ order.number }}, {{#if pending}}…{{/if}}, {{#each items}} — passes through untouched, and SendGrid processes it at send time as normal.

Does Temway sync my SendGrid contacts or suppression list? No. Temway is design-and-push only. Contacts, sender authentication, suppression management, and send settings live entirely in SendGrid. Temway creates a template; your application code decides who receives it.

What SendGrid plan do I need? You need a SendGrid API key with access to the Templates API, available across SendGrid’s plans. Beyond that, send volume and feature access depend on your SendGrid tier — check SendGrid’s current pricing for specifics; that’s a SendGrid question, not a Temway one.
