What you say today. What changes.
We sent 500 emails and got two replies — both asking us to stop.
Emails that read like a person wrote them, to clean lists only.
Our main domain got blacklisted and now our invoices go to spam.
Separate sending domains. Your main domain stays safe.
Someone replied 'interested' and we saw it four days later.
Every real reply reaches you in minutes, on WhatsApp.
How it works, step by step.
6 steps, and our team does them with you, so you never manage the software.
Step 1: We set up your sending domains and inboxes
Separate from your main domain, fully authenticated, each with a real name and signature.
Step 2: Warm-up runs for two weeks
Your inboxes build trust by emailing each other, replying, and rescuing anything that lands in spam.
Step 3: You give us your list — or we build one
Your prospects go into a sheet, or our Lead Finder builds the list for you. Every address is cleaned and verified.
Step 4: We write the campaign with you
Three short, plain-text steps in your voice, with several wordings for each.
Step 5: Cold sending starts small and ramps up
A few emails a day per inbox, rising over the following weeks, only in business hours.
Step 6: Replies come to you
Interested prospects trigger a WhatsApp alert and land in your CRM; opt-outs and bounces are handled automatically; a daily report shows exactly how it is going.
Everything it does. 48 features.
Sending accounts and domains
- Separate sending domains
- We set up look-alike domains for outreach (for example a "get" or "try" version of your brand) that redirect to your main website, so your real domain never sends cold email.
- Real inboxes with real names
- Each sending inbox is a named person with a photo and signature — not "info@" or "sales@", which mailbox providers filter harder.
- Email authentication set up for you
- We configure SPF, DKIM and DMARC on every sending domain and check that all three pass before any inbox is used.
- Per-inbox daily ceilings
- Each inbox has its own hard daily limit that no schedule can exceed, so adding more inboxes is how volume grows — safely.
- Add inboxes in minutes
- Growing from five inboxes to fifteen is a configuration change, not a rebuild.
Warm-up
- Automatic warm-up network
- Your inboxes email each other every day with natural, AI-written conversations on everyday business topics — so each one builds a history of real, two-way mail.
- Replies in the same thread
- Warm-up emails are answered inside the same conversation, a random number of times, the way real colleagues write back and forth.
- Opened, marked important and starred
- Received warm-up mail is opened, marked important, sometimes starred and filed away — the signals mailbox providers read as "this sender is wanted".
- Rescued from spam
- If a warm-up email ever lands in spam, it is moved back out within ten minutes and counted — the single strongest trust signal there is.
- Human timing
- Warm-up runs only in daytime hours, with random skips and random gaps, so it never looks like a machine on a timer.
- Every email genuinely different
- Each warm-up email gets a random topic and a random opening style, so the network never repeats itself.
Leads and list quality
- Import from a Google Sheet
- Drop your prospect list into a sheet — email, name, company, city, industry — and the engine takes it from there.
- Cleaning and de-duplication
- Blank, broken and duplicate addresses are removed before import. A column with a different heading ("E-mail", "Email Address") is still recognised.
- Email verification
- Every address is checked with a professional verification service. Only addresses confirmed as deliverable are ever emailed; risky, invalid and unknown ones are set aside.
- Catch-all handling
- Addresses on domains that accept everything are treated separately and tested in small batches, so they cannot drag down your bounce rate.
- Re-checks old lists
- Addresses verified more than a set number of days ago are re-verified before they are used again.
- Do-not-email lists
- Your own domains, your clients' domains and competitors can be blocked completely, alongside every person who ever opted out or bounced.
- Leads from Wakflow Lead Finder
- Prospect lists built by our Lead Finder flow straight in.
Campaigns and sequences
- Three-step sequences
- A first email and two follow-ups, spaced days apart, that stop the moment the prospect replies.
- Follow-ups in the same thread
- Follow-ups arrive as replies to your first email, so the prospect sees one tidy conversation — exactly as a salesperson would do it by hand.
- Rotating subjects and wording
- Each step has several subjects and bodies, with small word choices rotated inside them, so emails vary naturally from prospect to prospect.
- Personalised to each prospect
- Name, company, city and industry are filled in for every email, with graceful fallbacks, so a missing column never produces "Hi ," or a double space.
- Plain text, no tricks
- No images, no links in the first email and no tracking pixels. Emails look like one person writing to another — which is exactly why they reach the inbox.
- A polite opt-out in every email
- Every email ends with a simple line: reply "no" and we will not email you again.
- Industry-matched campaigns
- Run a different campaign for each industry you sell to; each prospect automatically gets the campaign written for their trade.
- Ready starter campaigns
- Proven-structure sequences for travel agencies, clinics and real estate to adapt, rather than starting from a blank page.
- Hindi, Hinglish or English
- Write your campaign in the language your prospects use.
Safe, human-paced sending
- A seven-week ramp
- New inboxes send nothing cold for two weeks, then three a day, climbing gradually to the daily ceiling by week seven.
- Business hours only
- Cold email goes out Monday to Saturday, 10 am to 6 pm India time, never on Sundays or at night.
- Random gaps and skipped rounds
- Sends happen at random moments inside the window, with random pauses before each one, and each day's quota varies a little — no fixed rhythm.
- One prospect, one sender
- Every follow-up comes from the same inbox that sent the first email, so the thread stays consistent.
- Never sent twice
- The engine makes it impossible to send the same step to the same person twice, even if something is retried.
Replies, bounces and opt-outs
- Reply detection every ten minutes
- New replies to your campaigns are picked up throughout the day.
- Instant WhatsApp alert for real replies
- When a prospect writes back, you get a WhatsApp message with who it is, so someone can respond while they are still at their desk.
- Sequence stops on any reply
- A reply of any kind ends that prospect's sequence immediately — no awkward follow-up after they have already answered.
- Opt-outs honoured forever
- "No", "unsubscribe" or "remove me" puts the address on the do-not-email list permanently.
- Bounces handled
- Bounced addresses are identified, marked and never tried again.
- Out-of-office aware
- An automatic "I'm on leave" reply does not end the sequence; the next email simply waits a few extra days.
- AI reply sorting
- Replies are sorted into interested, not interested, opt-out, out of office and wrong person, so the hot ones rise to the top.
- Interested replies to your CRM
- Prospects who reply with interest are created as leads in your CRM with the source "Cold Email", ready for your sales team.
Protection and monitoring
- Nightly health guard
- Each inbox's last seven days are checked every night. Too much spam, too many bounces, or thirty-plus sends with zero replies pauses that inbox's cold sending for a few days — warm-up keeps running so it can recover.
- Weekly inbox placement test
- Once a week, each inbox sends one real campaign-style email to a test mailbox, and the engine records whether it landed in Inbox, Promotions or Spam. Spam pauses that inbox automatically.
- One broken login pauses only one inbox
- If an inbox's login stops working, that inbox is paused for a day and you are told — every other inbox carries on.
- Error alerts on WhatsApp
- If any part of the engine fails, you get a WhatsApp message naming the step and the error.
- Emergency stop
- Every inbox can be paused in one step if you ever need to stop all sending.
Reports
- Daily WhatsApp report
- Every evening at 10 pm: per inbox, warm-up sent and received, spam rescued, cold emails sent, replies, bounces and opt-outs, plus seven-day spam and reply rates — with anything that needs attention at the top.
- Health at a glance
- Seven-day health for every inbox — spam rate, bounce rate, reply rate and last placement result — on request at any time.
- Nightly backup
- All campaign data, leads and history are backed up every night to secure off-server storage.
