EMAIL CAMPAIGNS, SIMPLIFIED

One platform.
Every sending route.

Build personalized campaigns with Gmail OAuth, provider App Passwords and verified Custom Domain SMTP—complete with previews, test sending, rotation and live delivery progress.

Everything needed from draft to delivery

A focused Windows desktop experience backed by centralized permissions and campaign controls.

Gmail Campaigns

Connect with OAuth JSON, authorize securely, manage multiple campaign workspaces, preview content and test before queueing.

App Password Sending

Connect supported email providers with dedicated app passwords and run complete campaigns without an API integration.

Custom Domain Rotation

Verify SMTP accounts, select eligible senders, set rotation intervals and follow per-account capacity.

Powerful Personalization

Use CSV fields, fixed values, sequences and randomized tags across subjects, message bodies, PDFs, QR codes and barcodes.

Rich Campaign Content

Compose normal or HTML messages, add inline images, attachments and personalized generated PDFs.

Live Progress

Watch queued, sent and failed results, understand errors and pause or resume supported operations with confidence.

Launch a campaign in four clear steps

The same familiar flow is available across Gmail, App Password and Custom Domain modules.

Connect a sender

Authorize Gmail, add an App Password account, or verify your Custom Domain SMTP details.

Add recipients

Paste addresses or import a recipient file with optional personalization columns.

Create and test

Set the sender name and subject, write normal or HTML content, add files and send a test copy.

Queue and monitor

Choose timing and rotation, queue the campaign, then follow delivery status from the activity view.

Built for teams that value control

Flexible enough for individual operators and structured enough for managed customer networks.

“Multiple workspaces make it easy to prepare one campaign while another is already running.”
