Liftinbox

Automated email warmup that improves deliverability and repairs sender reputation

Websubscriptionglobal

An automated email warmup web app that improves deliverability and repairs damaged sender reputation by gradually increasing sending volume over 30 days and routing messages to real inboxes that open, read, and reply. It also monitors SPF, DKIM and DMARC records daily with instant alerts if anything breaks, and is aimed at sales teams, email marketers and founders; it is not intended to improve deliverability for unsolicited spam campaigns.
