Inboxed
How it differs: no plan or tier. You pay only for emails that send, and there’s no contact cap, so a quiet month costs nothing and a long list doesn’t push you up a plan.
Best for: Senders whose volume is small or changes month to month, agencies that don’t want per-client fees, and teams that bring their own lead lists.
Pricing: $1 per 1,000 emails the receiving mail server accepts ($0.001 each), from a prepaid wallet. Card top-ups (opening soon) start at $5, the balance never expires, and top-ups aren’t refundable. No plans, seats or client fees.
Strengths
- Free warmup for every mailbox you connect, and free lead checks for every campaign lead
- A shared team inbox with assignment, private notes and approval before replies go out
- Client workspaces and a read-only client portal with no per-client fee
- AI first lines, rewrites and subject ideas on the AI account you connect (Google Gemini, Groq and OpenRouter have free tiers); Inboxed charges nothing for them
- Sends at each lead’s local time, can stop the rest of a company when anyone there replies, and pauses a mailbox above 5% bounces
- REST API, webhooks and an MCP server on every workspace
Limits to know
- No contact database: bring leads from a CSV, a Google Sheet, the API, or your own Apollo, Hunter or Snov.io account.
- Email only: no LinkedIn, calling or SMS steps.
- Reply sorting by intent and AI reply drafts are coming soon. Today the inbox is sorted by you, not by AI.
- A new product: no public reviews yet, and the warmup network is made only of customers’ own mailboxes, so it is small.
- Gmail connects with an app password; Outlook and Microsoft 365 connect in one click.
- A new workspace can send up to 300 emails in 24 hours until Inboxed raises the limit.
- At steady, high volume some flat plans cost less. The cost table on this page shows where.
