The only email warmup service with unlimited inboxes.
Standard SaaS tools charge you for every new address. Linki gives you unlimited inboxes and human-like warmup schedules on your own private infrastructure. Hosted by Opsily in 3 minutes.
Why traditional email warmup services are failing
Google and Yahoo changed the rules in early 2024. The old way of 'warming up' involved bots sending thousands of nonsensical emails to other bots. ESPs now recognize these artificial patterns instantly. If your email warmup service looks like a bot, your real emails will follow it straight to the spam folder.
The Linki Difference
Linki takes a different approach. Instead of high-volume noise, it uses human-first ramp-up logic. It simulates real user behavior with random delays and varied message structures. Because Linki is self-hosted on Opsily, you are not sharing an IP reputation with thousands of other spammy accounts. You build your own authority on your own terms.
- No Per-Inbox Tax: Most services charge $25 to $30 per month, per email. If you need to warm up 20 sub-domains, that is $600 fixed monthly. With Linki on Opsily, you pay one flat hosting fee.
- Lead Enrichment Included: Use built-in Apollo.io and LinkedIn scraping to find the right people while your accounts are warming up.
- Total Privacy: Your lead lists and outreach logs never sit on a third-party SaaS database.
