Email marketing that arrives.

What's inside

• build it with blocks!

  Visual email editor

  #editor

  Build with blocks and ready-made sections, check the desktop and mobile previews, and save the pieces you reuse. Emails are built with tables and inline styles, so they hold up in Gmail and Outlook.

• clean lists, no duplicates!

  Contacts, lists and segments

  #contacts

  Import a spreadsheet and Hemero checks every address, skips duplicates and leaves out anyone suppressed. Segments keep themselves up to date, like everyone who opened your last campaign.

• new subscribers!

  Signup forms

  #signup

  A hosted page, an embed or a popup, with double opt-in when you want proof of consent. New subscribers can start an automation the moment they confirm.

• it runs on its own!

  Automations

  #automation

  Welcome series, drips and follow-ups started by a signup, a list or a click. Waits, list changes and sends run on their own.

• real people, real numbers!

  Clear reports

  #analytics

  Deliveries, opens, clicks, bounces and unsubscribes for every campaign, plus the links people clicked. Clicks from link scanners are left out, so the numbers are people.

• just ask!
  Click to expand

  An assistant that helps with the work

  #ai

  Ask it to draft an email, fix a layout, import a list or explain a report. Every change it makes comes with an undo, and it never sends anything on its own.

• there is an API too!
  Click to expand

  API, webhooks and MCP

  #developers

  Send transactional email through a REST API, get a signed webhook for every event and connect AI tools to your account with MCP.

• ¡y en español!

  English and Spanish

  #languages

  The app, the system emails and the assistant speak both languages. Each person on your team picks their own.

Deliverability

A great email does nothing in the spam folder. Hemero watches the signals mailbox providers judge you by and steps in before a bad list hurts your reputation.

• Domain warm-up

  A new domain starts with small daily volumes that grow over two weeks, the way mailbox providers expect.

• Automatic pause

  When a campaign or automation starts bouncing or drawing spam complaints, it pauses itself and tells you why.

• List hygiene

  Contacts who stopped engaging are set aside, and every bounce, complaint and unsubscribe goes on your suppression list.

• Checks before you send

  Links, images, the sender and the unsubscribe link are reviewed before every send.

• One-click unsubscribe

  Every email carries the unsubscribe headers Gmail and Yahoo require from bulk senders.

Works with your tools

Connect the places your subscribers already are, without writing code.

• WordPress

  Put a signup popup or form on your site, and offer newsletter opt-in at WooCommerce checkout.

• Shopify

  Sync customers who agreed to marketing and add signup forms to your store.

• Stripe

  Bring customers who gave marketing consent at checkout into your lists automatically.

• Zapier

  Add contacts and react to events from thousands of other apps.

• Make

  Build visual workflows that add contacts and send emails.

• API

  A REST API and signed webhooks for your own software.

Why Hemero

In ancient Greece, the hemerodromoi were day-runners: messengers who carried news between cities on foot, often across great distances in a single day. Hemero takes its name from them, and the winged sandal in the logo is the messenger's. The job hasn't changed: get the message there.

Pricing

Monthly plans start at $19 for 25,000 emails, AI messages included. Without a plan, email is $1.50 per 1,000, bought in packages that never expire.

Questions

• Do I need my own domain?

  Yes. You send from an address on a domain you own and verify it by adding a few DNS records. That is what lets mailbox providers trust your email.

• Can I bring my list from another tool?

  Yes. Export your contacts as CSV or Excel and import them: Hemero recognises exports from the common email tools and maps the columns for you. Only import people who agreed to hear from you.

• What happens when someone unsubscribes?

  They are removed straight away and added to your suppression list, so no campaign or automation can reach them again unless they sign up again themselves.

• Can I send transactional email too?

  Yes. Receipts, password resets and notifications can go through the API, from the same verified domains and respecting the same suppression list as your campaigns.

• Is Hemero available in Spanish?

  Yes. The whole app, the system emails and the assistant are available in English and Spanish.
