The problem

What it solves for a business

For: Lead-generation agencies and founders running cold email for several clients at volume.

  • Agency sending tools cost hundreds of dollars a month, often behind a demo call and no trial.
  • Every rival charges per client for white-label portals or seats.
  • Replies across hundreds of mailboxes are hard to sort and answer on time.

How it works

OutreachSender, step by step

  1. 01

    Get approved

    New agencies say who they will email and why; an admin approves the account before anything can be sent.

  2. 02

    Connect mailboxes

    Add your own mailboxes by SMTP/IMAP, bulk CSV or one-click import from ReplyDak, with limits and a warm-up ramp.

  3. 03

    Import leads

    Upload a CSV with auto-mapped columns, or move campaigns and leads over from Instantly, Smartlead or EmailBison.

  4. 04

    Build the campaign

    Write steps with A/Z variants, spintax, variables and conditional content, scheduled in each lead's time zone.

  5. 05

    Work the inbox

    Replies land in one inbox, labelled by AI, with a draft answer you can send or edit.

  6. 06

    Report to clients

    Clients see a branded portal and get a weekly report with your agency's name, not ours.

Why switch

Advantages over EmailBison

No subscription or demo wall

Sign up and start; you pay only third-party costs such as ReplyDak mailboxes or a dedicated IP, at cost, shown line by line.

Portals included

Unlimited white-label client portals and weekly client reports at no extra charge.

AI in the inbox

Replies are labelled and drafted on Surge's own AI server; auto-send only passes drafts whose numbers, links and promises come from saved facts.

Use cases

How teams use OutreachSender

Agency with many clients

An agency runs one workspace per client, each with its own portal and weekly report.

Moving off a paid sequencer

A founder imports Smartlead campaigns and keeps sending without a monthly fee.

Reply handling

An SDR clears the inbox by label and sends the AI drafts after a quick check.

Mailboxes from ReplyDak

A team buys mailboxes in ReplyDak and imports them into OutreachSender in one click.

Under the hood

Where AI is used, and where it is not

The model

Surge's own Qwen server (qwen3.8-27b) for reply labels, draft replies, sequence writing, spintax and deliverability diagnosis. Claude only if switched on; not needed today. English output only.

Rules and code

Code decides sending limits, schedules, stop rules, bounce brake, auto-pause and the auto-send safety check (numbers, links and promise words must come from saved facts).

People in the loop

An admin approves each new agency; auto-send is off unless you choose labels, and it waits in a hold window you can cancel. Otherwise you send each reply.
