Contact Longtailo
The form goes to Joe Ellul-Turner, who makes Longtailo, and to nobody else. Answers come by email, usually within one working day. We will not pass your details to a vendor, a reseller or a lead buyer, we will not tell you what a keyword's search volume is because we hold no such data, and if your list is small enough that a spreadsheet is genuinely enough we will say so.
Email: enquiries@longtailo.com. Something broken or a billing question: Support. Asking whether the paid plan does a particular thing: talk to us about Longtailo.
It comes to the people who make Longtailo and nobody else. We do not pass enquiries to vendors, brokers or lead buyers, and we will say so if a spreadsheet is genuinely enough for a list your size.
