Platform

Built for volume.
Obsessed with the inbox.

Everything a high-volume sender needs in one place — from pushing millions of messages to making sure they don’t bounce, and from the first draft to the last automated follow-up.

Bulk sending at scale

High volume · Per-provider throttling

Push big campaigns without babysitting them. Sending is paced separately for each mailbox provider, so a surge to Gmail doesn’t get your mail slowed or filtered.

  • Millions of messages per campaign
  • Separate pacing for Gmail, Outlook and Yahoo
  • Live progress and delivery as it sends

Clean lists, better inboxing

List cleaning · Domain authentication

Bounces hurt your sender reputation. Every list is checked before it goes out, so you only send to addresses that exist — and your domains are set up the way inbox providers expect.

  • Verify every address before you send
  • Remove invalid, flag risky, merge duplicates
  • Guided SPF, DKIM and DMARC setup

Deliverability

Sent from Dubai.
Delivered everywhere.

Sending at volume only pays if it lands. Every campaign goes out through the same three safeguards.

  1. 01

    Paced per provider

    Gmail, Outlook and Yahoo each get their own sending speed, so volume spikes don’t trigger throttling or filtering.

  2. 02

    Cleaned before sending

    Invalid and risky addresses are caught before a campaign goes out — fewer bounces, a healthier reputation.

  3. 03

    Authenticated domains

    Guided SPF, DKIM and DMARC setup, so inbox providers can trust mail that says it’s from you.

How it works

From sign-up to first send in a day.

No migration project, no weeks of setup. Most teams send their first campaign the day they start.

  1. 01About 15 minutes

    Connect your domain

    Add your sending domain and follow the guided SPF, DKIM and DMARC setup. We check each record for you.

  2. 02Automatic

    Import and clean your list

    Upload a CSV or sync from your CRM. Every address is verified first, so invalid ones never get a send.

  3. 03Same day

    Design, send and track

    Build in the drag-and-drop editor or import HTML, hit send, and watch opens, clicks and bounces come in live.
