Sending limits and good sending practice
The daily sending figure, bounces, complaints and the suppression list explained simply, with habits that keep your mail out of spam folders.
Business E-mail is for your organisation's everyday mail: letters to parents, suppliers, boards and colleagues, receipts and notices. Receiving mail services such as Gmail watch how every sender behaves. Mail that people did not ask for, or that goes to many wrong addresses, harms your domain's reputation, and your future mail starts landing in spam. This guide explains the limits that apply and the habits that keep your mail trusted.
The limits, in plain words#
- Messages a day. Your plan includes a number of messages your organisation can send each day. Every message counts, whether sent from the webmail, a mail app, the JPX Mail app or the School ERP. Administration › Plan & add-ons shows today's count against the daily figure. When the day's figure is used up, sending stops until the next day, with the message The organisation has reached its daily sending limit — try again tomorrow or ask the provider to raise it. An administrator can buy more messages a day; see Storage, plans and buying more.
- Recipients in one message. One message can go to a limited number of addresses. The webmail tells you if you go over. Split large lists, or use the School ERP's communication tools for messages to all parents.
- Message size. Very large attachments are refused. Share large files another way.
Bounces, complaints and the suppression list#
- A bounce is a message coming back undelivered. A hard bounce means the address does not exist or will never accept mail. A soft bounce is temporary, for example a full mailbox.
- A complaint is when the person who received your message marked it as spam.
- The suppression list holds addresses that will not be written to again, so your organisation does not keep sending to bad addresses or to people who complained. A hard bounce stops an address for every organisation on the platform. A complaint stops it for your organisation.
If you send to a suppressed address, the message is not sent and you get a delivery-failure notice in your Inbox explaining why.
See and manage the list (administrators)#
- Open Administration and go to Delivery feedback.
- The first table lists suppressed addresses: Address, Scope (Every organisation or Your organisation), Reason, Since and Detail.
- The second table, when present, lists the bounces and complaints reported about your mail in the last 30 days.
- To allow mail to an address your organisation suppressed, select Remove on its row and confirm.
Remove an entry only when you know the address is correct and the person expects your mail. A second complaint counts against every organisation on the platform. Entries with the scope Every organisation show JPRAXC support instead of Remove; write to support@jpraxc.com if you believe such an address is now good.
When the table says No address is suppressed, every address your organisation writes to is still being delivered.
Good sending practice#
- Write only to people who gave you their address and expect your mail, such as parents who registered with the school.
- Never buy or borrow address lists, and never send advertising to people who did not ask for it.
- Keep your address lists clean: correct or remove addresses that bounce.
- Use a clear subject and a recognisable sender name, and say who you are in the message.
- For newsletters, tell people how to stop receiving them, and honour those requests.
- Do not put hundreds of addresses in To or Cc. Everyone sees everyone else's address, and receivers treat it as bulk mail.
- Send notices to all parents through the School ERP, which handles each parent separately and can use SMS, WhatsApp or ConnectX. See School ERP.
- Keep your domain's SPF, DKIM and DMARC records published. See Connect your domain.
- Keep passwords private and suspend any mailbox you think someone else is using.
Troubleshooting#
| What you see | What to do |
|---|---|
| Recipients say your mail went to spam | Check your DNS records, ask recipients to mark the message "not spam", and review the practice list above. |
| A delivery-failure notice says the address is on the suppression list | Check the address. If it is correct and the person expects your mail, an administrator can remove it in Delivery feedback (for your organisation's entries). |
| Sending stopped for the day | The daily figure is used up. Wait until tomorrow, or buy more messages a day. |
