FAQs

How does WarmySender ensure email deliverability?

WarmySender uses a peer-to-peer email warmup network where real mailboxes exchange conversations. It includes multi-turn threads, automatic spam-folder rescue, and per-mailbox health monitoring to train inbox placement and maintain a clean sender reputation.

What safety measures are in place for LinkedIn outreach?

LinkedIn accounts connect via Unipile OAuth without password sharing. New accounts undergo a multi-week warmup ramp with conservative daily limits, and each account is paired with a dedicated proxy. Real-time health monitoring auto-pauses accounts to prevent restrictions.

Does WarmySender offer a B2B lead database?

Yes, WarmySender includes a built-in B2B lead database covering verified contacts across the US and Canada. This database is searchable by industry, location, company size, and job title, aiding in targeted lead generation.
