Features

Everything you need to reach the inbox responsibly

Verification, campaigns, authenticated domains, tracking and reporting — managed from one account with one credit balance.

Audience

List verification

Upload CSVs, paste addresses or verify existing lists. Results are grouped into valid, invalid, risky, disposable, role-based and more.

Contacts & custom fields

Store only what you need: email, name, company, phone, country and your own custom fields.

Lists & tags

Organise contacts in lists, tag them in bulk and search or filter instantly.

Segments

Build dynamic segments with rules like country, tag, verification status or date added.

Streaming CSV import

Large files are processed in the background in chunks, with column mapping and duplicate handling.

Suppression list

Unsubscribes, hard bounces and complaints are suppressed automatically across all campaigns.

Campaigns

HTML, visual & plain-text editors

Write HTML with live preview, assemble blocks in the visual builder, or send plain text.

Template library

Start from marketing, newsletter, product, e-commerce, business, announcement and promotion layouts.

Merge tags with fallbacks

Personalise with {{first_name|there}} — the fallback is used when a field is empty.

Attachments

Attach documents with type and size validation. Files are stored privately.

Send now or schedule

See recipients and credit cost first, then send immediately or at a time you choose.

Pause, resume, cancel

Stay in control while sending. Cancelled campaigns return unsent credits automatically.

Delivered, opened, clicked, bounced and unsubscribed with a timeline and top links.

Bounce processing

Provider webhooks classify soft bounces, hard bounces, blocks and complaints.

Safeguards
