How it works

Three steps to your first mailing

1

Connect your mailbox

For example office@yourcompany.com. The panel has ready settings for popular providers and a “Test connection” button.

2

Set your design and templates

Logo, colours, banner and signature. Add fields to a template, e.g. {{date}} and {{code}}.

3

Send now or schedule

Pick a list, fill in the fields, check the preview and click “Send”, or choose a day and time.

The panel

One form instead of copying addresses into BCC

Choose a template, a mailbox and recipient lists. Fill in template fields, such as the topic or date, before sending.

The “Send” screen. The example company details are fictional.

Features

Everything you need for business emails

No HTML knowledge needed. The panel also works on phones and tablets.

Templates with fields

The same message every week? You only change the date and code. The panel will not send an email with an empty field.

Recipient lists

Paste addresses straight from Excel. The panel spots duplicates and invalid lines for you.

Personalisation

A recipient with a name on the list gets “Anna Smith,”, everyone else gets your greeting.

Scheduling

Choose a day and time, up to a year ahead. The email goes out on its own, and you can edit or cancel it.

Your brand

Logo, colours, banner, footer and a signature with graphics. Looks good in Gmail, Outlook and Apple Mail.

Team and permissions

Everyone has their own account and only the permissions you give them. The history shows who sent what.

Preview as the recipient sees it

Before you click “Send”, you see exactly what your customer will see, with and without a name.

Sending report

A copy with the recipient list and results lands in your mailbox: delivered, or an error with the reason.

Privacy

Every recipient sees only themselves

No more typing addresses into BCC or accidentally exposing your customer list. Everyone gets a separate email, and replies come straight back to you.

Security

Security you know from online banking

  • Two-factor login. A code from Google or Microsoft Authenticator. The owner can require it for everyone.
  • Password guessing protection. After 5 failed attempts per account or 8 from one IP address, access is blocked for 15 minutes.
  • Encrypted mailbox passwords. AES-256-GCM. Passwords are never shown in the panel.
  • Encrypted mail connection. TLS 1.2/1.3 with certificate verification.
  • Automatic logout and event log. After 2 hours of inactivity. Every login and change is recorded with its IP address.

FAQ

Frequently asked questions

Can recipients see each other’s addresses?

No. Everyone gets a separate email and sees only their own address in the “To” field.

Which address are emails sent from?

From your own mailbox, e.g. office@yourcompany.com. Replies reach you as usual.

Which email accounts can I connect?

Any mailbox with SMTP access: from your hosting provider, Gmail / Google Workspace, Microsoft 365, Zoho and others. The panel has ready settings for popular providers and a “Test connection” button.

Will my emails end up in spam?

Emails are sent from your domain like normal correspondence, which helps a lot. We recommend setting up SPF, DKIM and DMARC records for your domain. We will explain how.

How many recipients can I have?

In the online version it depends on your plan: 1,000, 10,000 or 50,000 recipients per month. One mailing goes to up to 300 recipients by default, which protects your mailbox from being blocked by your email provider. Your email provider’s own limits also apply.

What is the difference between the online and self-hosted versions?

Online: create an account and start right away, pay a subscription, updates are automatic. Self-hosted: pay once 350 €, install it on your own hosting, your data stays with you. 12 months of updates included, then optionally 100 € per year.

What if I do not renew updates for the self-hosted version?

The software keeps working without limits. You just do not get new versions and support. You can renew at any time.

How does the free trial work?

14 days free. You enter your card when you sign up. If you cancel before the trial ends, you pay nothing.

What happens if I do not renew my subscription?

Your data stays, but sending is paused until you renew.

Can I send emails with attachments?

Yes, up to 15 MB in total per mailing.
