Strong
Campaigns and email editorBeta

Email campaigns you build in minutes and measure honestly

Strong Send is a visual email editor, contacts and double opt-in lists, campaigns sent now or on a schedule, and delivery, open and click statistics. One-click unsubscribe in every email and a public API for your systems. Mailboxes on your company domain come with the same offer.

Beta: send.strong.ee is live, sign-in is through Strong ID. The trial includes the editor, contacts and test emails to your own addresses; sending campaigns opens with a plan, once the sender domain is verified.

Features

From template to report in one place

The whole path: sign-in, contacts, template, campaign, sending and statistics. Everything below already works on send.strong.ee.

  • Visual editor

    Build an email from blocks: headings, text, images, buttons, columns. The server renders the HTML and plain-text versions from the editor source (MJML) — the browser never sends finished HTML.

  • Contacts and CSV import

    Import contacts from CSV with name and language, search, add by hand. Delete a contact with all its data when the person asks (GDPR).

  • Double opt-in

    Double opt-in lists: a new subscriber gets an email and joins the list only after confirming. You see who confirmed, who is pending and who unsubscribed.

  • Scheduled campaigns

    Draft, test email to yourself, send now or at a set time. At send time the subject and content are frozen — editing the template never changes what was already sent.

  • Personalization

    Contact fields in the subject and body. The unsubscribe footer and the subscription confirmation are in the recipient's language.

  • One-click unsubscribe

    Every campaign email carries List-Unsubscribe and One-Click headers (RFC 8058) and an unsubscribe link in the footer. Unsubscribed contacts get no more campaigns.

  • Bounces and complaints

    Delivery reports and recipient complaints are processed automatically: permanently failing and complaining addresses are left out of the next sends.

  • Statistics

    Delivered, opens, clicks, bounces, complaints and unsubscribes — unique per recipient. Clicks per link, an hourly timeline, a daily overview of the organization.

Audience

Lists people really subscribe to

Confirmed subscription protects the sender's reputation and fits GDPR: only people who confirmed their address themselves get your campaigns.

  • CSV import with name and language columns
  • Subscription confirmation by a separate email in the contact's language
  • List statuses: confirmed, pending confirmation, unsubscribed
  • Unsubscribes, bounces and complaints are excluded from campaigns automatically
  • Add subscribers from your own form, too — through the API
Statistics

See what was read and what was clicked

Numbers are counted from each recipient's events, not estimated. Opens and clicks are unique; repeats are counted separately.

  • Delivered, opened, clicked, bounced, complaints, unsubscribed — as percentages and counts
  • Clicks on every link in the email
  • Hourly timeline of opens and clicks after sending
  • Daily overview of the organization: sent and delivered
  • Links in emails lead only to addresses from the email itself — they cannot be swapped
API

Emails from your systems, on the same engine

Public API v1 for your website, CRM or another Strong product: transactional emails, contacts, lists and campaigns. Described in OpenAPI at /api/v1/openapi.json.

  • A transactional email in one request — from a template or with your own subject and HTML
  • Idempotency key: a repeated request never sends the email twice
  • Message status and events: delivered, opened, clicked, bounced
  • Add to a list with double opt-in, following the list's rules
  • The organization token is shown once; only its hash is stored
Mailboxes

And everyday email on your own domain

Company mailboxes are part of the Strong Send offer: addresses on your domain, webmail in the browser and the mail apps you already use.

  • Mailboxes and aliases on the company domain
  • Webmail at web.strong.ee: threads, search, contacts
  • Desktop and phone mail apps over IMAP and SMTP
  • We set up SPF, DKIM and DMARC for your domain together
  • We create mailboxes on request — €3 per mailbox per month
Access and data

Campaigns without risk to your mail

The organization's rights and limits come from Strong Console, sign-in is through Strong ID. The app has no admin rights on the mail server or DNS.

  • Sign-in through Strong ID: passkeys and two-factor sign-in
  • Organizations with members and invitations — one organization's data is never visible to another
  • Strong's own campaigns go from a separate subdomain with SPF, DKIM and DMARC p=reject — the main mail's reputation is not affected
  • We connect the sender domain; Send checks its DNS records before sending
  • Tracking, unsubscribe and confirmation links are signed — they cannot be guessed or forged
  • Delete a contact with all its data — in the interface and through the API
Questions

Frequently asked questions

What happened to Strong Mail?

Strong Mail is now called Strong Send, after the main thing it does: campaigns and emails. Mailboxes on your domain remain part of the offer, and old /mail links lead here.

What can I do during the trial?

14 days: the editor, templates, up to 500 contacts, lists and test emails to your own addresses. Campaign sending is enabled with a plan, so the shared sending domain can't become a spam channel.

Can I send from my own domain?

Yes, with a plan. We connect your sender domain, you add the DNS records, and Strong Send checks SPF, DKIM and DMARC before it allows sending.

How do I connect a website or CRM?

Through public API v1 with an organization token: website form sign-ups into a confirmed list, transactional emails, starting a campaign and statistics. Described in OpenAPI.

How much does it cost?

Campaigns from €19 per month for up to 10,000 contacts, mailboxes €3 per mailbox per month, excluding VAT. Details and bundles are on the pricing page.
