SEO for Warmup Inbox
The story
Warmup Inbox warms up new email inboxes and helps cold outreach teams land in the inbox instead of spam.
I work with the Warmup Inbox team on SEO. I set a new content strategy and write the briefs, and our writers turn them into guides. Alongside the knowledge hub we went after product-led SEO: free tools, a cold email template database and a deliverability action plan that people search for and then use. I built the free tools myself.
Together, the tools, the database and the knowledge hub grew organic traffic.

Product-led SEO pages
Each of these pages answers a search with something people can use straight away, and the product sits one click from it.

Free email tools
23 free tools, from inbox placement tests to SPF and DMARC generators.

Cold email templates

Deliverability action plan
A few questions, then a plan: the domains and inboxes you need, what to fix first and what the setup costs.
