Automatic follow-ups
Days later, in the same thread, only if there is no reply.
HexaLabs Mailer
Email outreach that follows up for you.
Send personal outreach emails from your own Microsoft 365 mailbox, with follow-ups that go out days later in the same thread and stop the moment someone replies. Replies are sorted for you, and interested contacts land in your pipeline.
Your own mailbox
Sent from your Microsoft 365 address, not a bulk-mail server.
Stops on its own
On reply, unsubscribe or bounce. Never emails them again.
AI reply sorting
Interested, not now, out of office or unsubscribe.
Everything in the Mailer
From a contact list to a booked meeting.
Built for B2B outreach: a few hundred personal emails a day, not newsletters.
Contacts & lists
Group contacts by category and tags. Import CSV files, including Apollo, LinkedIn and Excel exports, with first names for a personal greeting.
Sequences
A first email plus follow-ups that go out a set number of days later if there is no reply. A follow-up with no subject is sent as a reply in the same thread.
Sends from your mailbox
Emails go out from your own Microsoft 365 mailbox, with your name and signature. Different campaigns can send from different mailboxes.
Smart scheduling
Start now or at a set time. Send windows in IST, weekdays only, holidays skipped, daily limits and a per-company limit, spread out in small batches.
Stops automatically
A reply, an unsubscribe (one-click link) or a bounce ends the sequence for that contact. Unsubscribed contacts can never be imported back in.
AI reply sorting
Replies are read and sorted: interested opens a deal, not now creates a reminder task, out of office delays the next email, unsubscribe stops it. You get an instant alert.
Inbox & pipeline
All replies in one inbox, answer from the app, and track interested contacts as deals with tasks.
Website enquiries in one place
Demo requests and enquiries from your website and store arrive as contacts and deals, and any cold emails to that person stop.
Protects your domain
Do-not-email list, address checks before sending, and campaigns pause on their own if bounces or unsubscribes climb.
Tracking & reports
Opens, clicks and replies per campaign and per step, an activity feed and a dashboard.
Call & LinkedIn steps
Add a call or LinkedIn step to a sequence and the Mailer creates a task for you at the right time.
Ready-made sequences
Starter sequences for lead outreach, demo follow-up, trial check-in and event invites, ready to edit.
How it works
Four steps from a list to a conversation.
Import your contacts
Upload a CSV from Apollo, LinkedIn or Excel. Tag the list and check the first names.
Write the sequence
A first email and two or three follow-ups, a few days apart, in your own words.
Schedule and send
Pick the start time and daily limit. Emails go out from your mailbox in small batches.
Reply to the interested
Follow-ups stop on any reply. Interested contacts show up in your inbox and pipeline.
