SO, LEAVE THE WARMING ACTIVITY ON US. Our infrastructure is built to support both LOW-TO-HIGH VOLUME SENDERS across all experience levels.

High Reputation in Google Postmaster Tools (GPT) for Business Plan (capture of 2025)**
Each SMTP server includes a Dedicated Aged Domain with a Good Sending History.
Have you ever wondered why your emails land in spam or have low open rates?
It's because mailbox providers like Google, Yahoo, Microsoft and others believe that sending spam-free content alone isn't enough for inbox delivery. They also evaluate the sending history of IP address and Domain. A good warm-up and deliverability strategy helps build this positive history, increasing the chances that your emails reach the inbox and achieve higher open rates.

Lower risk. Better results.
At a fraction of the cost.
Google and Microsoft can suspend your sending accounts at any time for TOS violations. Other cold email infrastructure services often resell those same accounts, adding a second layer of risk. IPwarmup.com runs on its own infrastructure, no middlemen, no platform dependency.
IPWARMUP.COM
Risk: Low
Own infrastructure, no platform dependency, 10+ years operating, dedicated IP and domain per customer.
GOOGLE / MICROSOFT
Risk: High
Cold email violates TOS. Accounts can be suspended without notice, taking your sending pipeline with them.
OTHER COLD INFRA
Risk: Medium
Many resell Google / Microsoft accounts. If the provider disappears or Google pulls the plug, your business stops.

Oh wait, are you a techie?
We've got special tools for you.

Every send, every defer, every soft-bounce, visible, filterable, exportable. No black boxes between you and the mailbox provider's response.
Open ELC →Take advantage of Pre-warmed Email Accounts
Using our Pre-warmed Email Accounts can make a big difference in the success of your email campaigns. These accounts already have a SOLID SENDING REPUTATION, which means your emails are more likely to avoid spam filters and land in inboxes.
Instead of starting from scratch with a fresh account, you can be using one that’s been carefully warmed up with consistent activity. Our pre-warmed accounts are designed to give you a head start, ensuring better email deliverability and higher open rates for your cold email campaigns.
Disclaimer: We provide SMTP server/service that is primarily warmed up for mailbox provider (Google) by sending emails to build email history. Even though the SMTPs are warmed up, we can't commit inbox rate, spam rate, open rates, ip or domain reputation/score, click rate, sending volume (minute, hourly, daily, weekly or monthly), engagement rate or profit/return on investment. As we have no control on some of the key factors such as mailbox provider’s algorithms/spam filters, content in the emails you send or quality of your email lists (recipients). Acceptability/deliverability/placement of emails with mailbox providers depends on your sending activity and how you utilize the smtp service. If you are sending quality emails to your own list (double opt-in with permission) you can have positive results (acceptability & deliverability). But if you send SPAM to a rented/purchased list or increase sending volume suddenly then you might not get the desired results (engagement) and that can even lead to being blocked or blacklisted by Mailbox Providers or RBLs.
*SenderScore.org: IP addresses assigned to you with SMTP server may or may not have a history on the SenderScore platform. We make no guarantees regarding the specific score of any IP address at the time of order delivery. While we try to assign IP address with a SenderScore above 75, but achieving and maintaining such a score depends on various factors such as sending activity, acceptance & deliverability.
**Google Postmaster Tools/GPT: Since January 2023, we do not support or connect our smtp servers with google postmaster tools (aka gpt) because of the reported bugs in the said platform. The concerning bugs cause two major issues: (1) wrong statistics such as spam rate, domain/ip reputation (2) statistics not generated such as spam rate, domain/ip reputation even after sending thousands of emails. So to avoid any misunderstanding of sending activity, even if requested by customer google postmaster tools (aka gpt) access will not be shared with anyone including but not limited to the customer.
***Optimised for 1 Million Per Hour Speed: This feature is only available for senders who have opted for enterprise plan (from start not upgraded from pro plan) and send emails to double opt-in subscribers, so that MTA (Message Transfer Agent) on SMTP server doesn't have to hold emails in the queue. (queue: emails waiting in the smtp server to be accepted by mailbox providers servers because of blocks, ISP restrictions, spamtraps, RBL lisitings, etc.)
