Step 4 - Connect your sender

This is the fastest path from a blank Inboxlee account to a mailbox ready to send. If you are new, start here. The whole flow takes about two minutes of attention plus 5–30 minutes of background DNS propagation.

Step 1 - Create your workspace

Go to inboxlee.com/signup. Sign up with a work email or Google SSO. Name your workspace after your company or outbound team - this becomes the default tag on every domain and mailbox you provision. No credit card is required to create the account.

After verification, you land on the dashboard. You enter card details at the end of the MagicLee flow via Stripe Checkout when you confirm your first order - no card needed up front.

Step 2 - Run MagicLee

MagicLee is the 9-step provisioning wizard. You can run it from the dashboard or directly from inboxlee.com after sign-in. The flow is linear - each step locks before the next becomes available, so you cannot skip the safety checks.

Step 1 of 9: choose buy-new-domain or migrate-existing.

Step 2 of 9: search for an available domain - we surface .com first because cold-email .com renewals are cheapest.

Step 3 of 9: pick the mailbox provider - Google Workspace today, Microsoft 365 in private testing.

Step 4 of 9: set the mailbox count per domain. The wizard caps at 3 because of the deliverability ceiling - see the dedicated post on this rule.

Step 5 of 9: name the mailboxes. We auto-generate first.last variants; you can override per row.

Step 6 of 9: DNS - SPF, DKIM 2048-bit, DMARC quarantine, MX. Inboxlee writes all four; you do not edit a record.

Step 7 of 9: optional forwarding and bounce-handling configuration.

Step 8 of 9: review the cart and complete payment via Stripe Checkout.

Step 9 of 9: live provisioning - the dashboard shows real-time status as the domain registers, DNS propagates, and the mailbox spins up.

Step 3 - Wait for DNS

DNS propagation typically completes in 5–30 minutes. Inboxlee polls every 60 seconds against the actual mailbox provider (not just public DNS), so a mailbox is only marked "live" once Workspace itself has confirmed DKIM verification. That avoids the false-positive of a record being globally cached but not yet picked up by Google.

You will get an email when the mailbox is live, plus a one-time secure link with the credentials. The link expires 24 hours after order completion.

Step 4 - Connect your sender

Once your mailbox is live, head to Integrations and connect Smartlead, Instantly, Lemlist, or Apollo with one click. From that moment Inboxlee tracks warmup-day, daily volume, and curve per mailbox via the sender API key.

New domain, fresh DKIM key, no campaign history? Warm for 14 days at 5 to 20 emails per day before sending real cold campaigns. Your sender tool drives the warmup; Inboxlee tracks the curve.
