FAQ

Frequently asked questions

Everything you need to know about using Leaderr to sell more guest posts and link insertions.

What is Leaderr?

Leaderr is an email client built for the SEO community. It is made for people who sell guest posts and link insertions on their websites. You can manage all of your outreach mailboxes in one inbox, warm them up for better inbox placement, and receive replies from the buyer campaigns we run for you.

Is Leaderr really free?

Yes. Managing your mailboxes, email warm-up and our buyer outreach campaigns are free of cost.

Who is Leaderr for?

Publishers and site owners who sell guest posts or sponsored content, sellers who offer link insertions and niche edits, and outreach teams that manage many mailboxes at once.

What is email warm-up and why do I need it?

Email providers are cautious with new or rarely used mailboxes, so their messages often land in spam. Warm-up builds a mailbox's sending reputation by gradually increasing its daily activity. A warmed-up mailbox gets far better inbox placement for your pitches and replies.

How do your buyer campaigns work?

We run outreach campaigns to SEO agencies, link builders and brands that buy guest posts and link insertions. When a buyer is interested, the conversation comes straight into your Leaderr inbox, so you just reply with your offer.

Which email accounts can I connect?

Leaderr is built for professional email on your own domain, like editor@yoursite.com. Connect the domain mailboxes you use for each of your sites and manage them side by side in one inbox.

How do I get help or contact support?

Email us at contact@leaderr.io for anything: help getting set up, account or billing questions, privacy requests or feedback. One address for everything.
