A newsletter platform for creators and small teams
Hemero covers the whole life of a newsletter: a signup form that confirms subscribers, an editor, scheduling, reports and list clean-up. It does not host a public archive or take payments, and this page is clear about that.
How to create a newsletter with Hemero
Verify your sending domain
You send from an address on a domain you own, which you verify by adding a few DNS records. That is what lets mailbox providers trust your email. A new domain is warmed up with small daily volumes that grow over two weeks.
Create a signup form
Make a signup form, choose the list new subscribers join and share it as a hosted page, an embed or a popup. Double opt-in is on by default: each person gets an email with a confirmation link and is subscribed only after clicking it.
Write the issue
Use the visual editor: start from a template, add text, images and buttons, and check the desktop and mobile previews. The assistant can draft a first version if you ask.
Test, then send or schedule
Send yourself a test, read the pre-send check, then send now or schedule for later. You can A/B test two subject lines on part of your list.
Read the report
See deliveries, opens, clicks, bounces and unsubscribes in the report. Opens are an estimate, since some mail apps open everything and others nothing, so clicks tell you more.
Double opt-in, as Hemero does it
With double opt-in a subscriber is pending until they confirm, and a pending contact is never emailed. The confirmation link works for 7 days. If someone who unsubscribed types their address into your form again, they have to confirm again, even if the form is set to single opt-in. Addresses that bounced or complained cannot be subscribed through a form.
Hemero also checks the address when someone signs up: it rejects badly typed or disposable domains and suggests a fix for common typos such as a misspelled popular provider.
Keeping your list healthy
Every unsubscribe, bounce and spam complaint goes on your suppression list, the addresses you must never email again, and no campaign or automation can reach them. Every send includes an unsubscribe link, and you can design the page people land on.
You can also set a rule to stop emailing subscribers who never engage: they are marked inactive and skipped, and they come back if they subscribe again. Hemero re-checks the email domains of your subscribers every month. And when you send, you can choose to send only to the contacts most likely to engage. More on deliverability.
Moving a newsletter from another platform
Export your subscribers as a CSV and import it. Hemero recognises exports from Substack, beehiiv, Kit (ConvertKit) and Mailchimp, among others, and matches the columns and opt-out status for you. Paid-subscriber status does not carry over, because Hemero has no paid subscriptions: everyone arrives as an ordinary contact.
What Hemero does not do
There is no public archive page for past issues, no paid subscriptions and no referral program. If you want to publish to the web or charge readers, pair Hemero with your own site or pick a tool built for that. If you have a website, the WordPress plugin puts your signup form on it.
What a newsletter costs
Monthly plans start at $19 for 25,000 emails. Each recipient of each send counts as one email, so a weekly newsletter to 1,000 people uses about 4,000 emails a month. If you send less often, packages at $1.50 per 1,000 emails never expire. Your list size does not set the price. See pricing.
Questions
What is the best way to start a newsletter?
Verify a domain, create a signup form with double opt-in, write your first issue in the editor, send yourself a test and schedule it. Hemero guides you through each of those steps.
Does Hemero have a public archive of past issues?
No. Issues are sent by email, and Hemero does not publish a web archive. If you want one, publish the content on your own site.
Can I charge for my newsletter with Hemero?
No. Hemero has no paid subscriptions. It is built for sending email to people who signed up for free.
Can I move my Substack or beehiiv subscribers?
Yes. Export a CSV from the platform and import it. Hemero recognises Substack, beehiiv and Kit exports. Paid status does not transfer.
How do I keep my list clean?
Use double opt-in, let Hemero add bounces, complaints and unsubscribes to your suppression list, and turn on the rule that marks subscribers who never engage as inactive.
How much does it cost to send a weekly newsletter?
Each recipient of each send counts once. Weekly to 1,000 people is about 4,000 emails a month, which fits a monthly plan from $19 for 25,000 emails.
