Can I email only some customers, not all of them?

Yes. Target by location and account status, or switch to manual mode and hand-pick specific clients. The recipient list is built from your live client data.

Are the emails personalized?

Yes. Merge fields such as the customer name and account number are filled in per recipient, so each person receives a message addressed to them.

Do I know how many people will get the message?

Yes. A live recipient count shows exactly how many customers with an email address match your selection before you confirm the send.

Will a large send slow down the app?

No. Messages are queued and delivered in the background, so sending to a large audience does not block your work.

How bulk messaging works

When a tower goes down or a price changes, you need to reach the right customers now, not export a spreadsheet into a separate email tool. ISPbox mass messaging lets you compose once, target clients by location and status or pick them by hand, personalize with merge fields, and queue delivery to everyone with an email address, all from the client list you already run.

Target by filter or by hand

Choose recipients by location and account status, or switch to manual mode and hand-pick individual clients. Either way ISPbox resolves the audience from your live client data, so the list is always current and only customers with an email address are included.

Compose once, personalize per client

Write one subject and body, then drop in merge fields such as the customer name or account number. Each recipient receives a version with their own details filled in, and a preview shows how the message renders before you send.

Preview the count, then queue delivery

Before anything goes out, a live recipient count tells you exactly how many customers will be reached. On confirm, the message is queued and delivered in the background, so a large send never blocks your screen.

Works with Client Communication, Customer Portal, ISP CRM

02 Why this feature matters

Built for high-speed ISP operations

Reach the Right Customers, Not Everyone

Filter by location and account status so a message lands only with the customers it is meant for, instead of a blanket blast.

One Screen, No Exports

Skip the CSV export into a separate email tool. Compose, target, and send straight from the client list you already manage.

Personal at Scale

Merge fields drop each customer name, account number and details into the message, so a mass email still reads one to one.

Know Before You Send

A live recipient count shows exactly how many customers with an email address will receive the message before you confirm.
