Built for founders, operators, and lean GTM teams
Cold outreach that feels crafted, not sprayed.
Sendloom turns your spreadsheet, template, and connected Gmail sender into one clean launch surface. Import lists, map fields, find missing contact emails with your own API key from hunter.io, choose plain text, HTML, or structured JSON templates, enhance subject lines and email copy with AI, add attachments, track runs, and keep delivery history in the same place the sequence actually lives.

Why it feels different
A launch surface designed for signal, not volume theater.
Great outreach products don’t just blast faster. They help small teams stay precise while the audience, message, and sender all change underneath them. Sendloom was shaped around that operator reality.
Write in the format your team actually wants.
Switch between plain text, HTML, and structured JSON inside the same template editor. Sendloom renders each one into a clean email preview while keeping merge variables and inline AI help intact.

Find the right inbox before you launch.
Run name-plus-domain lookups or domain-wide searches from the same dashboard, then plug your own API key from hunter.io into Sendloom so the finder stays inside your workflow instead of becoming another tab.

Stay fast without acting reckless.
Sendloom keeps retries, tracking links, and send-window guardrails in the loop so campaigns feel deliberate even when the list is moving quickly.

Launch from a connected Gmail sender.
Use the mailbox you already trust, connect Google in minutes, and move from upload to launch with a single operator dashboard instead of five disconnected tools.

Workflow
From raw list to a live sequence, without the usual glue work.
Built for the person actually shipping the campaign.
If you’re the one importing leads, checking the sender, fixing the template, and watching the run at the same time, the interface should help you think clearly. That’s the bar this product is trying to hit.
The page layout, delivery primitives, and tracking model are all there to reduce hesitation at launch time and make the sequence easier to trust afterward.
Import your audience
Upload a spreadsheet, detect columns instantly, and keep the row data structured for every downstream send.
Find missing emails when the list is incomplete
Use name-plus-domain lookups or domain search with your own API key from hunter.io, then keep those results inside the same operator flow.
Choose the message system
Pair the list with a template, sender, and attachment strategy, then write in plain text, HTML, or JSON with inline AI help before you save.
Launch and watch the run
Immediate sequences begin processing from the app itself, and status updates stay visible while the run moves.
Keep the sequence honest
Clicks, opens, and retry states stay attached to the campaign so your next send starts smarter.
Walk in with a spreadsheet. Walk out with a running sequence.
Connect Gmail, create the campaign, and start testing the full flow from a single login. The fastest way to understand Sendloom is to put your own list through it.
