Market demand via keyword data:

• “how to unsubscribe from emails in bulk” – 1 600 monthly searches, difficulty 11 (excellent).
• “bulk unsubscribe email” – 590 monthly searches, difficulty 20.
• “unsubscribe from emails gmail” – 1 300 searches, difficulty 15.
• All above pass the ≥500 volume & <30 difficulty rule, indicating measurable intent.
• Brand keyword “Unroll Me” draws 12 100 searches/month – confirms a popular solution people actively look for.

Existing paid competitors (proof people pay):

• LeaveMeAlone.app – $2.50/mo and higher plans (SaaS, privacy-friendly but not self-hosted).
• Clean.email, Mailstrom, Trimbox – subscription pricing, no self-host, store OAuth tokens in cloud.
• GoodByEmail – advertises an on-prem/self-host offer for business; contact-for-pricing, validates B2B willingness to pay.
• Unroll.Me – free but monetises user data; constant criticism over privacy – creates positioning gap for “privacy-first”.
• Open-source hobby projects (Hatchet, Gmail-Unsubscribe script, BulkUnsubscribe) show DIY interest but are unfinished → gap for polished product.
