Neuctra Mailer
Email template maker

An email template builder that sends from your own SMTP

Design HTML emails from ready-made starters or from scratch, then send them through your own Gmail, Outlook, Zoho or SES account. Build with blocks or write custom HTML, add your brand once, personalize every email with variables, and preview the real rendered email as you type.

Start from a ready-made email template

Every starter shows a live preview with your brand and is fully editable.

  • Welcome email for new subscribers
  • Monthly newsletter with a banner and stories
  • Product launch announcement
  • Sale with a discount code
  • Order confirmation with an order table
  • Event and webinar invite
  • We miss you win-back email
  • Feedback request with a 1 to 5 rating
  • Blank, or your own custom HTML

Build emails from blocks

Add up to 40 blocks: headings, text, buttons, images, dividers, spacers, social links and custom HTML snippets. Fold, move, duplicate or remove any block, and style each one with its own size, alignment and color.

Design settings apply to the whole email: page and content colors, an email-safe font, width from 480 to 800 px, corner radius, padding, a border and your logo.

Or write your own HTML email

Paste a full HTML email or a fragment. Switch between blocks and custom HTML at any time without losing work, because both versions are kept. A plain-text version is generated for you.

Personalize every email with variables

Variables work in the subject, preview text, blocks and HTML. Use a fallback so an empty name still reads well.

Subject: Your October picks, {{first_name|there}}

Hi {{first_name|there}},
Here is what we shipped this month.

Not interested? {{unsubscribe_url}}

Preview, test and send

  • The preview is the real rendered email, at desktop or phone width
  • Send yourself a test before anyone else sees it
  • Your brand color, logo, address and footer are applied for you
  • Every template ends with an unsubscribe link
  • Scripts and javascript: links are removed, and subscriber names are escaped

Frequently asked questions

Are the email templates responsive?
Yes. You can preview each template at desktop and phone width before sending. For custom HTML, use inline styles and tables for the widest mail app support.
Can I use my own HTML email template?
Yes. Choose Custom HTML and paste a full email or a fragment of up to 100,000 characters. The unsubscribe footer is added unless your HTML places {{unsubscribe_url}} itself.
Where are templates used?
Send a template to the people you pick in a list from the Send tab, with a status for each person. A template can also be a list's welcome email, sent the moment someone subscribes from your app, and you can send yourself a test of any template.
