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.
Deliverability & insight
Sending domains

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
Campaigns with unusually high bounce or complaint rates pause automatically.
