For ptd.net addresses
PTD Email Settings and PenTeleData Email App for ptd.net in One Inbox
PenTeleData makes no mail app. Here are the ptd.net server settings, checked live from outside PenTeleData's network, and a way to read that address beside Gmail and work mail on any computer.
Tested live · Normal password · Nothing to install
In short
There is no PenTeleData email app. A ptd.net address uses one server, promail.ptd.net, for both directions: IMAP on port 993 with SSL coming in, and SMTP on port 587 with authentication going out. PenTeleData's guides use the part of the address before @ptd.net as the user name, the password is case sensitive, and no app password is involved. Webmail is at webmail.ptd.net.
PTD email server settings
Every ptd.net setting in one table
The host comes from PenTeleData's own server information page. The last column is what each port did when we connected from our servers in the United States in October 2026.

| Setting | Host | Port and encryption | Our live test |
|---|---|---|---|
| Incoming, IMAP | promail.ptd.net | 993, SSL | Answered, plain password sign in offered |
| Incoming, IMAP alternative | promail.ptd.net | 143, STARTTLS | Answered, STARTTLS offered |
| Incoming, POP | promail.ptd.net | 995 with SSL, or 110 | Both answered |
| Outgoing, SMTP | promail.ptd.net | 587, STARTTLS, authentication on | Answered, STARTTLS and LOGIN sign in offered |
| Outgoing, old port | promail.ptd.net | 25 | PenTeleData's own guides move it to 587 |
| User name | The part before @ptd.net, case sensitive | Same for incoming and outgoing | |
| Webmail | webmail.ptd.net | Opens My PenTeleData Webmail | |
PenTeleData's server page names a single host for everything, promail.ptd.net, and mail.ptd.net resolves to the same address. Its older guides set up POP and port 143; IMAP on 993 with SSL is the better choice today because every device then sees the same folders, and the connection is encrypted from the first byte. We did not test port 465, because our own servers do not send on that port.
Why this address matters
The old PTD address that is still on everything
PenTeleData is the Pennsylvania internet provider behind the ptd.net addresses, and those addresses go back to its dial up years. Plenty of households and small businesses still use one for the things that matter most: the bank, the insurance agent, the accountant, the customers of a shop or a contracting business.
The trouble is that it rarely lives alone. The same person usually has a Gmail account from a phone, an iCloud address from an iPad, and a work mailbox. My PenTeleData Webmail shows one mailbox per sign in, and the phone's Mail app does not travel to the office PC. So the ptd.net address gets checked last, and that is where the overdue invoice sits.
A mail program that holds several accounts fixes that. If you want the settings entered once and the same list on every computer, an email client for multiple accounts that runs in a browser is the shortest route.
Measured in October 2026
PTD mail answered from outside its own network
We looked up the ptd.net mail records and opened connections to promail.ptd.net from our servers in the United States, the same way any outside mail program would.
Incoming
Port 993
- IMAP ready with SSL
- Port 143 with STARTTLS also open
- POP on 995 and 110 answered too
Outgoing
Port 587
- promail.ptd.net greeted and offered STARTTLS
- LOGIN sign in offered
- Same host as incoming mail
Sign in
Password
- Plain password sign in on IMAP
- No app password system
- Capital letters count
PenTeleData moved its email to a newer hosting platform, and the server that answered us is that new one. A test on one day is not a promise, but it shows a ptd.net address works over standard IMAP and SMTP from anywhere, with a normal password. Other regional providers behave differently; the Armstrong email settings page and the Comporium email settings page cover two of them.
PTD mailbox rules
Four facts that decide how a ptd.net mailbox behaves
These come from PenTeleData's own support pages. The first one is the one that causes bounced mail.
5 GB
Storage included with each mailbox. Past it, PenTeleData returns all new mail to the sender.
1 host
promail.ptd.net handles incoming and outgoing mail, so there is only one name to get right.
587
The outgoing port PenTeleData's guides switch to, replacing 25, which many networks block.
Aa
User names and passwords are case sensitive, which explains a lot of failed setups.
Every way to read a PTD mailbox
Six routes to PTD email on a computer or phone, compared
The questions that decide it are whether the route runs on the machines you use, and whether it holds your other addresses too.
Swipe to see all columns →
| Route to PTD mail | Runs on | Holds other accounts too | Survives Gmail's January 2027 change | Cost |
|---|---|---|---|---|
| Inboxes | Windows, macOS, Linux, ChromeOS, in a browser tab | Yes, one merged board | Yes, reads ptd.net in place over IMAP | 49 dollars a month for five mailboxes, half that billed yearly |
| My PenTeleData Webmail | Any browser, any machine | No, one mailbox per sign in | Yes | Included with the mailbox |
| Gmail checking mail from other accounts | Anywhere Gmail runs | Yes, inside Gmail | No, Google drops this fetch for third party addresses | No license fee |
| Classic Outlook | Windows and Mac, with a Microsoft 365 or Office license | Yes, as separate folder trees | Yes | Part of a Microsoft 365 or Office purchase |
| iPhone and Mac Mail | Apple devices only | Yes, with an All Inboxes view | Yes | Included with the operating system |
| Thunderbird | Windows, macOS, Linux, Android | Yes, through Unified Folders | Yes | Open source, no license fee |
Google's January 2027 change removes Gmailify, the POP fetch of other accounts and Send as for third party addresses; the detail is on our check mail from other accounts page. For one address on one shared computer, My PenTeleData Webmail is the honest answer.
When the setup fails
Four reasons PTD email stops working in a mail program
Outgoing authentication is off
Mail arrives and nothing sends, usually as soon as you are away from home. The Promail server requires a login on every network. Turn on My outgoing server requires authentication and reuse the incoming user name and password.
A capital letter in the wrong place
PenTeleData treats user names and passwords as case sensitive. A phone that capitalized the first letter of the user name on its own is enough to fail. Retype both by hand.
Outgoing still on port 25
Old setups from the Windows Mail years used port 25, which hotels, offices and phone networks block. PenTeleData's own guide changes it to 587. Do that before you touch the password.
A mailbox past 5 GB
When the mailbox passes its allowance, senders get their mail back and you see nothing new. Check E-mail Usage in the customer panel and clear old Sent and Trash folders.
If none of those fit, sign in at webmail.ptd.net with the same user name and password. If webmail refuses it too, the problem is the account or the password rather than the program, and PenTeleData technical support at (800) 281-3564 is the next call.
Where a browser client fits
What Inboxes does with a PTD mailbox
The pitch is narrow on purpose. It is the one thing PenTeleData does not offer, which is the ptd.net address and your newer ones in one list.
PTD beside everything else
The ptd.net address sits in the same stream as Gmail, Yahoo, iCloud and your own domain, with the source account on every row, so it is no longer the inbox you check last.
The settings entered once
Enter promail.ptd.net one time, with a separate user name field for PenTeleData's short user name. After that the office PC, the laptop and a borrowed computer show the same inbox.
Your normal password
Connecting takes the user name, the password and the host from the table. No app password to generate and nothing to install on any machine.
A category on every message
Each message arrives labeled Important, Newsletter, Notification, Spam or Other. On an address used for twenty years, sorting before you read is what keeps the bank notice from drowning.
Unaffected by the Gmail change
If you read ptd.net inside Gmail today, that fetch stops in January 2027. Reading it in place over IMAP does not depend on Gmail at all.
Replies from the right address
An answer to a message on your PTD address goes out through promail.ptd.net with your login, so customers and suppliers see the address they already know.
Three steps, and no download
Connecting a PTD address to one board
Nothing here moves your mail. PenTeleData keeps the copy, and the board reads it over IMAP.
Step 01
Confirm the password
Sign in once at webmail.ptd.net. If the user name and password work there, capitals included, they will work over IMAP.
Step 02
Add the mailbox
Enter the address, the user name and the password, then promail.ptd.net on 993 incoming and on 587 outgoing.
Step 03
Add the rest and read one board
Repeat for Gmail, Yahoo, iCloud or your own domain. Everything lands in one stream with the source on each row.
Where this is the wrong answer
What Inboxes does not do
It does not host your mail. The mailbox lives at PenTeleData and depends on your PenTeleData account. We read it; we do not host it. If the account closes, the address stops working everywhere, including here.
It will not connect a Microsoft mailbox. We sign in with a user name and password or app password. Microsoft has removed that kind of sign in from Microsoft 365 work mail and has said it intends to rely only on OAuth for Outlook.com too, so an outlook.com, hotmail.com or Microsoft 365 address will not connect here. ptd.net, Gmail, Yahoo, AOL, iCloud and own domain mailboxes do.
No calendar, no contacts, no offline mode. It runs in a browser tab and wants a connection. For reading mail with no signal, Thunderbird, Apple Mail and classic Outlook keep a local copy.
There is no permanent tier that costs nothing. Plans start at 49 dollars a month for five mailboxes, or half that billed yearly. If one ptd.net address on one home computer is the whole job, the settings above and the mail app you already have will do it. The case for paying starts when you read several mailboxes on several machines, or want the volume itself cut down.
FAQ
Questions people ask about PTD email
What are the PTD email settings?
Incoming and outgoing mail both use promail.ptd.net. For IMAP use port 993 with SSL, or 143 with STARTTLS. For outgoing mail use port 587 with authentication turned on. PenTeleData guides use the part of your address before @ptd.net as the user name, and the password is case sensitive.
Is there a PenTeleData email app?
No. PenTeleData does not publish a mail app of its own for iPhone, Android, Windows or Mac. Its support pages walk you through general mail programs such as Windows Mail, Outlook, Mac Mail and the Android email app, and it offers My PenTeleData Webmail in the browser.
What is the PTD IMAP server?
The PTD IMAP server is promail.ptd.net. In our October 2026 test from servers in the United States it answered on port 993 with SSL and on port 143 with STARTTLS, and offered a plain password sign in. The name mail.ptd.net points at the same machine.
What is the PTD SMTP server?
The PTD SMTP server is also promail.ptd.net, and it requires a login. PenTeleData tells customers to use port 587 rather than 25. In our test, port 587 answered and offered STARTTLS and LOGIN sign in.
What are the ptd.net email settings for iPhone?
Open Settings, then Apps, then Mail, then Mail Accounts, then Add Account, then Other, then Add Mail Account. Pick IMAP and enter promail.ptd.net as both the incoming and outgoing host, your user name and your case sensitive password, and leave SSL on. Set outgoing mail to port 587 if the phone asks.
What are the ptd.net email settings for Android?
In the Android email app choose manual setup, then IMAP rather than POP, so the phone and your computer show the same folders. Enter promail.ptd.net for incoming on port 993 with SSL and for outgoing on port 587, turn on Require sign in, and use the same user name and password for both.
How do I set up PTD email in Outlook?
In classic Outlook choose File, then Add Account, then Advanced options, then Let me set up my account manually, and pick IMAP. Use promail.ptd.net on port 993 with SSL incoming and promail.ptd.net on port 587 with STARTTLS outgoing, and turn on outgoing authentication with the same user name and password.
What is the PenTeleData webmail address?
My PenTeleData Webmail opens at webmail.ptd.net, which leads to the same promail.ptd.net server. It shows one mailbox per sign in, with folders, filters, a calendar and an auto responder, so it suits checking one address and gets slow when you read several addresses each day.
Why is my PTD email not working?
Check four things in order. Outgoing authentication must be on, the outgoing port should be 587 and not 25, the password must match webmail exactly including capital letters, and the mailbox must be under 5 GB. PenTeleData returns new mail to the sender once a mailbox passes its 5 GB allowance.
Do I need an app password for PTD email?
No. PenTeleData asks for your normal mailbox password in every mail program and does not issue app passwords. That makes a ptd.net address simpler to connect than Gmail, Yahoo or AOL, which refuse your real password in third party programs.
Can I send PTD email from another internet provider?
Yes. PenTeleData says you can send from your ptd.net address on any network by pointing your mail program at the Promail server with SMTP authentication on. Without the login, mail sent from a hotel, an office or a phone network is refused.
Can I read my PTD email in Gmail?
Today you can, through the Gmail setting that checks mail from other accounts over POP. Google has announced it removes that POP fetch, Gmailify and Send as for third party addresses in January 2027, so a ptd.net address pulled into Gmail that way stops updating. Reading the mailbox in place over IMAP is not affected.
