Users Blamed the Platform. The Platform Had No Answer.
Sendcopy.ai is an AI-assisted outreach platform built for sales teams, agencies, and founders. Their product is designed to help users start real conversations. But there was a structural tension in the model.
Users were launching new domains, starting cold campaigns immediately, and expecting results. No warmup. No authentication checks. No reputation history. Just new domains hitting cold inboxes at volume.
When a user's emails land in spam, they don't blame their domain setup. They blame the platform. Deliverability failures weren't Sendcopy.ai's fault in isolation, but they were Sendcopy.ai's problem to solve.

Warmed and stabilized Sendcopy.ai's own sending domains first. Onboarding emails and platform notifications running clean before user domains were touched.
New users' sending domains enter E-Warmup's warmup infrastructure at signup. Every user launches with a warmed domain instead of a cold one.
Inbox placement health, sender reputation scores, and blacklist status surfaced directly inside Sendcopy.ai's product. Deliverability visible without a separate tool.
5,000+ real inboxes and 100+ blacklist monitoring running in the background for the entire user base. Scales as Sendcopy.ai grows.

After E-Warmup Inbox Integration
The framing shifted from "deliverability is a user problem" to "deliverability is a platform feature." When users get results from day one because their domains are warmed and monitored, the product looks better. Churn goes down. Word of mouth improves.
Sendcopy.ai didn't just solve a support problem. They turned a liability into something they talk about in their own marketing.
“We were losing users in the first 30 days because their outreach wasn't landing. Once we brought E-Warmup in at the infrastructure level, that problem essentially disappeared. It became a feature we talk about in our own marketing.”

E-Warmup helped them to increase their email deliverability 🎉



I have been using different e-mail warm up services and E-warmup is the best in the game. I avoid spam at all cost because of these guys. Thank you so much for being there for me when my company needs you most.

Inbox placement from 63% to 99% in a short time, over experience with e-warmup is outstanding, i learnt how to use the warmup settings for fixing mails vs maintaining high deliverability vs warmup. I switched from smartlead’s warmup to here and got the result what i expected basically. Customer support was really helpful.

I have used other warmup tools, but the best thing about e-warmup is some extra features that were not available in the other tools. E-warmup shows accurate data on email health, bounce rate (which is not found on other tools). Also, their AI read emulation feature is great.
