When to Go Custom: Email Templates for Marketers, Gmail/Outlook Notes
An email template is a reusable email layout that separates structure from content, so a brand can send consistent, on-brand messages without rebuilding an email from scratch every time. It saves production time, keeps every send looking like it came from the same company, and lets a single small team support hundreds of campaigns. The rest of this guide covers the types, the platform-specific steps, and the practical checklist that keeps templates working.
TL;DR:
- Static templates are suitable for consistent content like policy updates, while dynamic templates are necessary for personalized offers or recommendations.
- Building templates around common workflows such as cart recovery can significantly reduce abandonment rates by automating timely follow-ups.
- Testing templates across major inboxes and devices is critical to prevent rendering issues, ensure deliverability, and maintain brand consistency over time.
- Modular or component templates streamline updates across campaigns and support scalable growth for large or high-frequency email programs.
- A managed, custom template system becomes essential once sending volumes increase beyond what platform defaults can support efficiently and consistently.

What Actually Makes Up an Email Template?
A template is really three layers stacked together: a fixed layout, a set of brand elements, and open zones where content changes. The layout controls where the header, image blocks, and buttons sit. Brand elements, like your logo, colors, and fonts, stay locked so nobody accidentally sends an email in the wrong shade of blue. The editable zones are where a marketer drops in new copy, images, or offers without touching anything structural.
Templates split into two operational categories. Static templates hold the same content for every recipient, useful for a one-time announcement or a policy update. Dynamic templates pull in data, a first name, a product recommendation, a loyalty tier, so each recipient sees a slightly different version of the same shell. Klaviyo, Mailchimp, and most modern email platforms support both.
The reason teams bother with any of this is governance. When five people are sending emails and only one of them owns the master layout, mistakes creep in fast: broken links, missing unsubscribe footers, logos that got stretched. A modular template system fixes that by making the structure someone’s responsibility while everyone else edits inside guardrails.
- Layout: fixed grid and spacing
- Brand elements: locked colors, fonts, logo placement
- Content zones: editable copy, images, offers
- Governance: one owner for the master file, many editors for content
What Types of Email Templates Should You Actually Use?
Not every message needs the same template. Matching the type to the job is what separates a template library that gets used from one that gets ignored after week two.
- Newsletter and promotional templates. These are the visual, image-heavy layouts built for sales announcements, product launches, and regular content roundups. They lean on hero images, multiple content blocks, and a clear call-to-action button.
- Transactional templates. Order confirmations, shipping updates, password resets. These are triggered by system events rather than a marketer hitting send, and they carry real constraints: the data has to be accurate, and required fields like order number or tracking link can’t be optional.
- Plain-text templates. No design, minimal formatting, built to look like a real person typed it. These work best for outreach, sales follow-ups, or founder-style updates where a polished layout would actually hurt trust.
- Modular or component templates. Built from swappable blocks, a hero module here, a product grid there, so a design team updates one component and it propagates across every campaign using it. This is the approach that scales past a handful of monthly sends.
Most brands end up running at least three of these types at once, often without realizing they’re separate categories with separate rules.
What Are the Real Benefits of Using Email Templates?
The most obvious benefit is time. A marketer building an email from a blank canvas every week loses hours to formatting decisions that a template already answered. Templates also enforce brand and legal compliance automatically, since the unsubscribe link and company address are already baked into the footer rather than something someone has to remember.
Scalability is the less obvious win. A modular template lets a five-person team run the email program of a fifty-person team, because updating one module updates every campaign that uses it.
Where templates show up in practice:
- Onboarding sequences for new subscribers or customers
- Promotional campaigns and seasonal sales
- Cart recovery flows, a category worth taking seriously given that global cart abandonment rates hover around 70%
- Customer support and post-purchase follow-ups
That abandonment figure alone explains why so many ecommerce teams build a dedicated cart-recovery template before almost anything else.
How Do You Create and Save a Template in Gmail or Outlook?
The general flow is the same no matter which platform you use: pick a layout, add your brand elements, mark the parts that stay editable, save it, then test before you rely on it.
- Choose a base layout, either a blank canvas or a pre-built option from your platform.
- Lock in brand colors, fonts, and logo placement so they can’t drift between sends.
- Mark which sections are meant to change (headlines, offers, images).
- Save the template somewhere your whole team can find it.
- Send a test to yourself and a coworker before it goes live.
In Gmail, templates live under Settings. Turn on the Templates feature, then compose a message the way you want it saved, open the compose window’s More options menu, and save it as a new template. From there you can insert any saved template directly from compose. If you want a template to go out automatically, pair it with a Gmail filter rather than sending it manually every time.
In Outlook, there are two distinct tools, and mixing them up wastes time. Mail Templates save a full message, formatting, attachments, and all, and work best for repeatable full emails like a weekly report. The My Templates add-in, by contrast, stores short reusable text snippets, better suited to quick replies than full campaigns. Some of this functionality depends on a Microsoft 365 subscription, so check your plan before you build a workflow around a feature you don’t actually have.
Pro Tip: Build your first template around your most-repeated email, not your most complicated one. The habit of reusing it matters more than the design.
What Should Every Good Template Include?
A template earns its keep by having the right components in the right order, and by following a short list of rules that keep it working across every inbox it lands in.
Core components: preheader text, header with logo, a hero section, one or more body modules, a clear call-to-action, and a footer carrying the unsubscribe link and company address.
Accessibility, deliverability, and personalization rules:
- Add ALT text to every image, since some inboxes block images by default
- Keep color contrast high enough that text reads clearly against its background
- Use a logical heading order so screen readers can follow the structure
- Keep the HTML lean and host images externally rather than embedding them
- Set up proper email authentication and always include a working unsubscribe link
- Add personalization (name, past purchase, browsing behavior) only in the zones built for it, never by hand-editing the master layout
Pro Tip: Test your template with images turned off before you send it. If the message still makes sense without a single graphic, your deliverability will hold up in more inboxes.
How Do You Test and Maintain an Email Template Over Time?
A template that worked perfectly six months ago can quietly break today, a font update, a new email client, a rebrand nobody told the design team about. Testing catches that before subscribers do.
Run rendering checks across major inboxes and device sizes before any template goes into rotation, and again after any brand change. Confirm inbox placement and run a basic spam check, since certain image ratios and link patterns quietly hurt deliverability. Assign one owner to the master file so changes go through one person instead of five, and schedule a full audit at least once a year, or immediately after evidence of rendering failures.
| Check | Frequency |
|---|---|
| Cross-client rendering | Before launch, after any edit |
| Mobile display | Before launch |
| Spam/inbox placement | Before launch |
| Full template audit | Annually, or after a rebrand |
What Do Quick Starter Templates Actually Look Like?
You don’t need a design team to sketch a working template. Here are four bare-bones structures worth adapting today.
- Newsletter: Preheader → logo header → hero image with headline → three content blocks → single CTA button → footer.
- Transactional: Subject line with order number → confirmation message → itemized details → tracking link → support contact → footer.
- Outreach (plain-text): Personal greeting → one-sentence reason for reaching out → single ask → signature. No images, no design.
- Cart reminder: Subject referencing the specific item → product image and price → urgency line → CTA to complete checkout → footer.
Swap in your own brand voice and colors before sending, and keep plain-text for anything meant to feel personal. Save the designed layouts for anything meant to feel like a brand, not a person.
When Is It Time to Move Beyond Platform Templates?
Platform templates work fine at low volume. But once you’re sending dozens of campaigns a month across multiple flows, welcome series, cart recovery, post-purchase, a custom modular system pays for itself: it plugs directly into automated workflows, cuts approval time, and gives one person clear ownership over brand governance instead of five people guessing.
An Email Marketer’s Honest Rule of Thumb
Speed matters, but a broken brand template that goes out fast is worse than a solid one that takes an extra day. My rule: build the master template once, test it hard, then let content move fast inside it. Start with your highest-volume send, not your fanciest idea.

Get Custom Templates and Managed Klaviyo Flows Built for You
Take-action is the alternative to piecing together templates on your own: instead of hunting for the right layout every month, you get a custom modular system built once, governed properly, and plugged straight into your Klaviyo automations.
Building templates yourself works until volume outpaces your time, and that’s usually right around the point when welcome flows, abandoned cart sequences, and post-purchase automations all need their own tested layout. Take-action builds those templates as part of full Klaviyo flow setup and campaign management, handling the governance, the cross-client testing, and the ongoing maintenance so nothing breaks quietly six months from now. If your current templates feel like they’re held together with good intentions, get in touch and see what a managed setup looks like for your brand.
