Features
Cold mail isn't just a science.
It became an art!
Stop Landing in Spam. Start Landing in Inbox.
Cold outreach fails when sender reputation is weak.
We continuously warm up your mailboxes with natural email activity, real replies, and engagement signals — so inbox providers see you as trusted.
No complicated setup. No technical guesswork. Just better deliverability.
Add Unlimited Mailboxes up to 50 per domain
Add as many mailboxes as you want under your domain.
Just input your SMTP / IMAP credentials and we handle the rest.
Other tools charge $15–$30 per mailbox — we don’t.

Why Inbox Placement Tests Matter
Sending cold emails without placement testing is like running ads without tracking conversions.
You don’t actually know where your emails land — inbox, promotions, or spam.
Inbox placement tests show you the truth before you launch a campaign.
What Placement Tests Reveal
Whether your emails land in Inbox or Spam
Provider-by-provider results (Google, Microsoft, others)
If links or CTAs hurt deliverability
If your domain reputation is slipping
If a mailbox needs more warmup before sending
If a new template is risky
If signature or footer changes affect placement
Instead of guessing — you measure.
Why High-Volume Senders Test Often
Serious cold email operators run placement tests:
Before every campaign
After copy changes
After domain or DNS updates
When scaling volume
When adding links
When switching signatures
When rotating mailboxes
Because one bad send can damage reputation for weeks.
The Hidden Cost of Skipping Tests
Without placement testing you risk:
Burning domains
Damaging mailbox reputation
Lower reply rates
Wasted lead lists
False “copy doesn’t work” conclusions
Campaigns that fail silently in spam
Most senders only discover problems after results drop.
Placement tests catch problems early.

TESTIMONIALS
Hear What Our Clients Have to Say
“We moved 32 mailboxes into VeryColdMail and inbox placement improved within two weeks. The warmup behavior looks natural and the spam recovery actually works. The placement tests alone saved one of our campaign domains before we burned it.”
Duarte Braga, CTO at PTT4U
“Other tools charge per mailbox, which killed our margins. Here we run all inboxes under one plan and control the warmup volume per account. Setup took minutes and deliverability is noticeably more stable across Google and Microsoft.”
Patricia Tello, Owner at Nowtics
“The inbox placement tests are the killer feature. We now test every template before launch and catch problems early. Our reply rates went up simply because we’re actually landing in primary instead of guessing.”
Bob Greenberg, CEO at RFinder
Frequently Asked Questions
Your Questions, Answered Clearly
How long does it take to properly warm up a mailbox?
Most mailboxes build a healthy sending reputation in about 14 days.
However, warmup should continue for as long as you plan to send cold emails.
Sender reputation is not a one-time setup — it’s ongoing. Continuous warmup activity keeps engagement signals strong and helps maintain inbox placement over time.
Do I need to keep warmup running after the first 14 days?
Yes. If you stop warmup while continuing cold outreach, reputation signals can weaken.
We recommend keeping warmup active in the background for the entire time you send campaigns.
Think of warmup as reputation maintenance — not just reputation building.
Can I upload mailboxes in bulk?
Yes. You can upload bulk CSV files with your SMTP and IMAP account details.
This makes it easy to onboard dozens of mailboxes at once instead of adding them manually. You can also edit, pause, or remove mailboxes anytime after import.
What kind of mailboxes are in your warmup network?
Our warmup network includes aged, professional Google and Microsoft business accounts that actively send, receive, reply, and engage with messages.
These accounts generate natural engagement patterns — including opens, replies, and spam-folder recovery actions — which help build stronger trust signals with inbox providers.
What happens if my emails are landing in spam?
Our system performs active recovery actions when warmup emails land in spam folders.
Messages are moved to inbox, marked as important, and replied to — helping retrain filtering systems and improve future placement.
Recovery is gradual, but consistent engagement signals improve results over time.
Can I control how many warmup emails are sent per day?
You control:
Warmup emails per day
Ramp-up speed
Reply percentage
Sending pattern behavior
You can adjust settings anytime.
Does warmup affect my normal email sending?
No. Warmup runs alongside your normal sending activity and is designed to look natural to inbox providers.
It supports your sender reputation while you run outreach — not interfere with it.
How can I recognize and filter warmup emails in my inbox?
We automatically include tracking codes in warmup message headers and subjects so you can easily identify them.
This allows you to create inbox rules or filters to:
Label warmup emails
Move them into a folder
Keep them separate from real conversations
Monitor warmup activity if you want visibility
The tracking codes don’t affect deliverability — they’re only there to help you stay organized and distinguish warmup traffic from your normal email.
Is this compatible with my current sending software?
Yes — Verycoldmail is fully compatible with any platform that sends and receives email through standard SMTP/IMAP mailboxes.
There’s no complex integration, plugin, or API setup required. Simply connect your mailbox credentials, and our system runs safely in parallel with your existing sending software without interrupting your campaigns, automations, or workflows.
You keep using your current tools exactly as you do today — we work quietly in the background to strengthen your sender reputation and improve inbox placement.
Compatible with all major sending platforms, including:
• Brevo (Sendinblue)
• Mailchimp
• HubSpot
• Hunter Campaigns
• Lemlist
• Instantly
• Smartlead
• Apollo
• Woodpecker
• Reply.io
• GMass
• Mailshake
• ActiveCampaign
• Klaviyo
• SendGrid
• Amazon SES

Run Your First Warmup Today
Too many outreach campaigns fail not because of bad offers or weak copy — but because emails never reach the primary inbox. Sender reputation, mailbox behavior, and deliverability signals decide results long before prospects read your message.
We built VeryColdMail to give senders real control over those signals.
