40+ Ways to Destroy
the Competition.

Multi-step sequences that run on autopilot

Day 2 follow-up. Day 5 nudge. Day 10 breakup. Set it once and forget it. Per-contact tracking tells you exactly where every prospect stands.

Drop in any contact list. Done.

CSV in. Emails out. Any columns — [FirstName], [Company], [WhateverYouWant]. No mapping wizards. No 45-minute setup. Just drag. Drop. Send.

Queue campaigns like a machine

Stack multiple campaigns. Run them in sequence. Pause and resume whenever you want. Your progress is always saved. Always.

Crash-proof. Restart-proof. Idiot-proof.

Close Outlook. Restart your PC. Lose internet. Come back. ColdPumper picks up exactly where it left off. Nothing lost. Ever.

Know where every single contact stands

Sent. Pending. Skipped. Failed. Full visibility at every step of every sequence. No guessing. No spreadsheets.

Throttling that actually works

Goes fast when it can. Slows down when it should. Stops before Microsoft even blinks. Your account stays clean. Always.

Natural sending waves, not robotic blasts

Sends in organic waves — fast, slow, pause, fast again — the way a real human would email throughout the day. Not a flat-rate fire hose.

Warm start (without the warmup BS)

Starts slow, ramps up gradually at the beginning of each campaign. Looks natural. Feels natural. Because it IS natural.

Built-in rest periods. Because even beasts need breaks.

Takes natural pauses between batches to keep everything flowing. You don't manage timing. You don't think about timing. It just works.

Multi-account rotation

Rotates across multiple user accounts automatically. Each with independent sending windows. Maximum safety. Maximum throughput.

Automatic domain spreading

Never hammers the same recipient domain in a row. Spreads your sends naturally so nothing looks suspicious. Ever.

Per-domain rate limits

Caps how many emails hit any single domain per hour. Spam filters never see a spike. Because there isn't one.

Auto-kill switch

Getting close to Microsoft's limits? ColdPumper STOPS. Automatically. Before anything bad happens. Your account is untouchable.

Outbox monitoring

Watches your outbox in real time. If anything backs up, it pauses instantly. No stuck emails. No queue overflows. No disasters.

Self-healing recovery

Stuck email? ColdPumper detects it, fixes it, and keeps going. No babysitting required. Your campaigns run while you sleep.

Word variation engine (spam filters HATE this)

Rewrites every email so no two are identical. Subject lines. Body copy. Everything. Can't pattern-match what doesn't have a pattern.

48 battle-tested templates

Across 10 categories — intros, follow-ups, value props, social proof. Tested. Proven. Ready to deploy. Stop staring at a blank email.

A/B test like you mean it

Subject lines. Body copy. Both at once. Track which version gets replies. Kill the loser. Scale the winner. Simple.

Rich HTML emails — not plain text garbage

Import formatted templates with full HTML. Images. Formatting. The works. Your emails look professional because they ARE professional.

Auto-detects every mailbox you have

User mailboxes. Shared mailboxes. ColdPumper finds them all automatically. No manual configuration. No searching through admin panels.

Automatic rotation. You don't touch a thing.

Cycles through your shared mailboxes on its own. Different sender each time. Natural variation. While you do literally anything else.

Randomized order. No patterns. No flags.

Shuffles the mailbox rotation so it never follows the same predictable sequence. Looks completely natural because it IS completely natural.

SendGrid — plugged in, powered up

Connect your SendGrid account. Send through their pipes. Manage everything from inside Outlook. One dashboard to rule them all.

Mailgun — high volume, zero hassle

Plug in Mailgun for raw sending power. Full campaign management stays inside ColdPumper. No switching between apps.

Amazon SES — pennies per email, managed from Outlook

Connect SES for the most cost-effective high-volume delivery on earth. Alongside your M365 sends. Same dashboard.

Google Workspace — because why limit yourself?

Send through Google Workspace accounts alongside M365. Mix and match providers. One interface. Maximum flexibility.

Any SMTP server. Literally anything.

Got a custom SMTP setup? Plug it in. ColdPumper doesn't discriminate. If it sends email, we connect to it.

Watch it happen. Live.

Real-time dashboard. Color-coded. Every email sent. Every pause. Every status update. More addictive than stock tickers.

Receipts on everything

Full CSV exports. Who got sent. Who got skipped. Which A/B variant. What step. What status. Client asks for a report? 3 seconds.

Per-contact tracking with full history

Complete history for every contact across all campaign steps. A/B variant tracking included. Know everything. Guess nothing.

Free Email Verification — Kill Your Verification Bill

Every email gets verified before ColdPumper sends to it. MX lookup. Mailbox check. The works. Built directly into the sending engine — not a separate step, not a separate tool, not a separate bill. ZeroBounce charges $0.008 per email. MillionVerifier wants $37 per 100K. NeverBounce is $0.003-$0.01 each. ColdPumper? $0. Always. Verify 10 emails or 10 million. Same price. Free.

LinkedIn Email Extractor — Your Prospecting Weapon

Open LinkedIn or Sales Navigator. Find your targets. ColdPumper extracts verified emails, job titles, company info, and more — powered by our own proprietary database cross-referenced against LinkedIn's real-time data. Not some stale CSV from a data broker. Not crowd-sourced garbage. Fresh, verified, ready-to-send contacts. Apollo charges $49/month for 'enrichment credits'. Lusha wants $79. RocketReach is $53. ColdPumper does it built-in. No credits. No per-lookup fees. Your LinkedIn. Your data. Your pipeline.

Automated Bounce Intelligence — It Gets Smarter Every Day

Here's what other tools do when an email bounces: nothing. The bad address stays in your list. Next campaign? It bounces AGAIN. Your sender reputation drops. Your domain gets flagged. Rinse. Repeat. Here's what ColdPumper does: the SECOND an email bounces, that address is blacklisted. Not just from this campaign — from EVERY campaign. Past, present, and future. Automatically. No manual cleanup. No re-uploading 'cleaned' lists. No spreadsheet surgery. The result? The more campaigns you run, the CLEANER your sends get. Your bounce rate drops over time. Your reputation improves. Microsoft trusts you more. Your inbox placement goes UP. Every other tool stays as dumb as the day you installed it. ColdPumper gets smarter. Every. Single. Send.
