ArcWatch

Every mailbox watched, guarded and healed

ArcWatch watches every domain, mailbox and link you send with, checks every email before it leaves, and heals what breaks. When something goes wrong, you get what, where and why, before it turns into a sequencer error.

The problem

By the time replies drop, the damage is weeks old

Something breaks long before anyone sees it in the numbers, and nothing you look at every day points to it.

The cause comes first

A list goes stale or a link gets listed. Replies fall weeks later, and they are the first number anyone checks.

Someone else asks first

A client or your manager asks why replies dropped before you have an answer, or anything to show them.

Every dashboard says healthy

Your sequencer counts sends and warmup. A suspended mailbox or a listed domain never shows up there.

How ArcWatch works

It watches, guards and heals on its own

It watches every domain, mailbox and link all day and checks every email before it leaves. Every problem comes with its cause and its fix.

Every domain and mailbox, watched all day

One screen for the whole fleet, with the few things that need you at the top.

  • Suspensions spotted within the hour
  • Listings flagged the same day
  • Records checked again after setup

A cause with every alert

Each problem arrives once, with what broke, why, and what ArcWatch already did about it. Nobody digs through logs to find out.

  • What broke, why, and what was done
  • One issue per cause, not one per mailbox
  • Resolved issues stay on record

Cause

One tracking link, used by one campaign.

Done

Three mailboxes paused at 11:52, 46 emails held.

After

Sending resumed at 14:05. Nothing bounced.

Bad email stopped before it leaves

Send check looks at each email on its way out. One that would hurt your reputation stops there, with the reason attached.

  • Stopped before it leaves
  • A reason with every stopped email
  • Nothing to change in your sequencer

Contained before it spreads

When a domain or a link gets listed, the mailboxes it touches pause and their email waits until sending is safe again.

  • The affected mailboxes pause on their own
  • Their email waits until it is safe
  • Sending resumes once it is safe
