Drag and drop email editor: design emails without code
Build a newsletter, a promo or a welcome email by dragging blocks onto the page. Start from a template, set your colors and fonts once, and reuse the pieces you like.
What the email template builder does
Hemero builds an email out of blocks: headings, text, images, buttons, columns, social links, a footer and more. You drag a block onto the email, click it to change its settings, and drag it again to reorder. You see the result as you work, and there is nothing to code.
Under the hood the email is built with tables and inline styles, the way email apps such as Gmail and Outlook expect, instead of web features they tend to ignore.
The same editor works in two places: in Templates, where you keep reusable designs, and inside a campaign, where you edit your own copy of a template without changing the original.
What you can put in an email
Basic blocks
#basicsHeading, Text, Image, Button, Divider, Spacer, Columns and Social links, plus a Footer and a raw HTML block for the rare case you need it.
Ready-made sections
#sectionsHeader, Hero, Features, Stats, Testimonial, Pricing, Products, Gallery and Article. Drop one in and replace the text and images with yours.
More content
#contentVideo (it shows a thumbnail that opens the video, because email apps can't play video), Countdown, Coupon, Quote, Bullet and Numbered lists, Table, Progress bar, Image + text, Signature and Alert.
Personalization
#merge-tagsMerge tags insert a contact's first name, last name, full name, email or any custom attribute. Add a fallback, such as "there" when a first name is missing, so no email starts with a blank.
One theme for the whole email
#themeThe Theme panel sets the colors, font, width and corner radius once, so every block follows the same style.
How to build an email in Hemero
Create a template
Open Templates and click New template. Name it, choose a starting point (Blank, Newsletter, Announcement, Product launch, Monthly newsletter, Store promo or Pricing update) and click Create & open builder.
Add blocks
The Blocks panel groups blocks as Content, Media, Layout, Utility and Sections. Click a block to add it after the selected one, or drag it onto the email. Search by name if you know what you want.
Edit and style
Click a block to change its text, colors, spacing and links in the Properties panel, or type straight on the canvas. Open Theme to set the colors and fonts for the whole email.
Personalize
Use the Merge tag menu to insert a first name or any custom attribute. Keep the Footer block: it carries your unsubscribe link and postal address, which email rules expect.
Preview
Switch between Editor, HTML and Preview, and between Desktop and Mobile. You can also preview the email as one of your contacts to see their real name in place of the merge tags.
Check and test
Run the Content check for spam-filter and inbox warnings, then use Send test to send it to up to five addresses. Test sends need a verified domain.
Save and use it
Save the template. Pick it in a campaign's Content step, or in an automation's Send email step. Every save is kept in Version history, so you can restore an earlier version.
Reusable blocks, undo and version history
Found a footer or a promo box you like? Use Save as reusable block on the block's toolbar. It then appears under Saved in the Blocks panel of every email in your organization.
Undo and Redo work as you edit. Version history keeps a version each time you save (autosaves count at most once every 10 minutes) and holds the latest 100, so you can preview an older one and restore it. Restoring first keeps the current version in the history, so you can switch back.
What it costs
The editor, templates, saved blocks and version history have no feature limits on any plan. Plans differ only in how many emails you send and how many AI messages are included: Starter is $19 a month for 25,000 emails. See pricing for the rest.
Want a first draft? The AI assistant can write or rework the email open in the editor, and you can undo what it changes.
Honest limits
Email apps are not browsers
Video can't play inside an email, so the Video block shows a thumbnail that links to the video. The Countdown block is an image drawn when the email is opened, and some apps keep images for a while.
Raw HTML is on you
The HTML block is pasted as is: scripts are removed and nothing else is checked. Test it in your own inboxes. The Content check flags custom HTML.
Fonts fall back
Email apps that can't load fonts such as Geist or Inter show a similar system font instead.
Test in real inboxes
The Desktop and Mobile previews help, but every email app renders a little differently. Send a test to yourself before a big send.
Questions
Do I need to know HTML to use the email editor?
No. You build with blocks and never touch code. If you want the finished HTML, the HTML view lets you copy it or download it as an .html file.
Can I start from a template instead of a blank page?
Yes. New templates start from Blank, Newsletter, Announcement, Product launch, Monthly newsletter, Store promo or Pricing update, and a campaign can start from any template you saved. A campaign gets its own copy, so editing it never changes the template.
Will my emails look right on a phone?
You can switch the preview between Desktop and Mobile while you edit. Because each email app renders a little differently, send a test to your own inboxes before a big send.
Can I undo a mistake or go back to an older version?
Yes. Undo and Redo work while you edit, and Version history lets you preview and restore any of the latest 100 saved versions.
Can I reuse a design in several campaigns?
Yes. Save it as a template and start each campaign from it. You can also save single blocks, such as a footer, and drop them into any email.
Does the editor cost extra?
No. It is included in every plan, with no limit on templates.
