Email marketing templates
When a template saves production time, when it makes every brand look the same, and the layout habits that read as spam.

A template is a constraint, not a brand
Templates exist because HTML email is still a pile of tables, image blocking, and Outlook quirks. A good one gives you a one-column width, a type scale that survives dark mode, a footer with address and unsubscribe, and a place for the actual sentence you came to write. That constraint is the value. The stock hero image of smiling strangers is not. ESP galleries from Mailchimp or Brevo are a starting point. Strip the stock photo before you send.
Use a template when several people will send and you need the footer to stay legal. Use one when you send often enough that rebuilding layout would steal the writing hour. Do not use one because the ESP dashboard opened on a gallery of seasonal themes. Those galleries are how unrelated brands ship the same purple banner and the same fake button.
Footer: address, unsubscribe
When templates start looking like junk
Mailbox filters and humans both react to the same tells: a giant image and almost no live text, too many competing buttons, URL shorteners, 'click here' repeated, and a preview pane that says 'Having trouble viewing this email?' as the first line. If your template requires the images to load before the message makes sense, people on mobile with images off get nothing. That pattern still shows up in 'professional' themes.
Identical structure every send can also train people to skim. If every campaign is hero, three columns, testimonial, CTA, you have built a banner ad. Vary the content even if the shell stays. A plain-text-looking note from a person should not wear the same chrome as a product drop.
What to lock versus what to rewrite
Lock the header logo, the footer, the unsubscribe, the physical address, and the max width. Rewrite the first screen every time: preheader, subject, and the opening paragraph. Those three decide whether anyone reaches the template at all. Locking them into 'This month from Acme' is how newsletters become wallpaper.
Coded custom templates make sense when you have a designer who will test in Gmail, Outlook, and Apple Mail, including dark mode. Drag-and-drop templates make sense when the writer is also the sender. Mixing a custom HTML paste into a builder that then wraps it twice is how you get nested tables and broken buttons. Pick one production path.
Accessibility is part of the template
Real alt text, link underlines or a second cue besides color, type large enough on a phone, and a contrast that still works when the client inverts colors. Screen readers hit your email. So do people who never load images. If the template cannot survive both, it is a picture, not a message.
Keep a text-only version. Many ESPs generate one. Read it. If it is a dump of links and leftover tracker URLs, fix the template until the text version is something you would send from a personal mailbox.
Common questions
Are free template marketplaces safe to use?
Only after you strip unknown tracking, replace the footer with your legal bits, and send tests. A free file can include leftover merge tags or images hosted on someone else's server that will die. Treat marketplace HTML as a sketch, not as production.
Should transactional mail use the marketing template?
Keep receipts and password resets much quieter. A shared header is fine. Promotional modules, social icon rows, and extra CTAs do not belong on a shipping notice. People should trust that message even if they never open a campaign.
