2. Channelswhere new users come from and what the traffic looks like
New-user source: Other (Direct / referral / email / paid). Similarweb has no data for this site, so channel shares cannot be given. The only channels the founder filled in on TrustMRR are word-of-mouth and affiliate; the homepage shows no referral program entry, only an article published 2025-10-19, 'Why cold email tools are getting banned & how we are not', for content-driven acquisition. In the sale notes the founder writes that revenue declined in 2026 and there has been 'no sales activity', which suggests the current customers are basically existing customers renewing and word of mouth, with no ongoing acquisition.
