Carla — saw Helix is doing the dispatch-board + mobile tech app combo, with a customer portal sitting on top. That's exactly the stack the residential HVAC outfits I work with end up cobbling together from three different vendors. Curious how Helix's customer portal handles the post-service follow-up — that's usually where the seams show. Worth a 15-minute swap?

Inside Mailuno
01 / Research
Drop in a list of business emails. Mailuno opens each prospect's site, scans the homepage and key sub-pages, and pulls the details a human would notice — what they sell, who they serve, and the language they use.
02 / Dispatch
Every email goes out on your schedule from your own connected inbox. Watch each send happen in real time, with per-lead status and the exact email that went out, all logged.
03 / Ingest
Drop in a CSV from Apollo. A TXT export from a scraper. A messy spreadsheet a VA sent over. JSON from your own pipeline. Mailuno figures out where the emails are.

04 / Deliverability
Cold email only works if it lands. Mailuno connects to your own Gmail, Outlook, or custom SMTP — never our shared infrastructure — so every send builds your sender reputation, not someone else's.
Built-in warmup keeps your inbox warm before and during campaigns. SPF, DKIM, and DMARC checks run on every connected mailbox. Daily send caps respect provider limits automatically.
Who it's for
Skip the SDR hire. Send 50 personalized first-touches before lunch.
Run multiple client workspaces under one bill. White-label the unsubscribe domain so your clients never see Mailuno.
Replace the “spray with {first_name}” sequences your reps copy from each other. Every email is custom.
Reach passive candidates with notes that actually reference their work.
Built for deliverability
Built for senders who care about reaching the inbox.
The difference
| Other tools | Mailuno |
|---|---|
| Spray-and-pray sequences | Reads each site first |
| {first_name} variables | Writes a real custom email |
| Generic templates | Zero templates required |
| You write the copy | The AI writes the copy |
| Pay per seat | Pay per lead generated |
Most cold email lands in spam or gets deleted unread. Mailuno reads first, so the email earns a reply.
