The use of services from GigaCloud Hosting, Inc [hereafter referred to as “GigaCloud Hosting”]
There is a 500 outgoing email hourly limit per
domain. This limit is also applied towards Mailman. If you send over this
amount in any hour, most of the e-mails will bounce back with an undeliverable
error. If this occurs, it will then take some time for your account to be able
to send again so we recommend waiting at least 1 hour after this issue occurs
to begin sending email again.
Many of our servers have a limit of 30
POP3/IMAP checks per hour per each user’s connecting IP address. If you go over
this you’re likely to get a wrong password error message or an error stating
“login incorrect”. If this occurs, please wait an hour and it will
automatically unblock you. To prevent this from happening again, please make
sure to disable auto checking or at least set it to something higher such as
once every 10 minutes.
Any mailing list larger than 5,000 addresses
will require a dedicated server or VPS hosting solution from us. Note: Dividing
one large list into smaller lists to get below this limit is not allowed.
There is also a limit to the number of Mailman
mailing lists permitted as follows (NOTE: This does not apply to other mailing
list programs such as PHPList. This only applies to Mailman.)
· Plane plan: 20
Mailman mailing lists
· Jet package: 25
Mailman mailing lists
· Rocket package:
50 Mailman mailing lists
2. Mailing Lists Rules
0. Any time you’re sending a message no matter
how large your e-mail list is you must throttle it. We recommend you throttle
it to at the very least sending 1 email every 8 seconds. (Sending 1 every 8
seconds would send 450 emails within 1 hour, keeping you below the 500 outgoing
email limit.) If the mailing list software you’re using does not allow you to throttle
you must switch to an application or script that will. We recommend PHPList,
which can be found in your CPanel, under Quickinstall.
IMPORTANT: If you do not throttle and you try
sending 500 emails, the server will try sending all 500 in 1 second which is
not possible on our shared servers. This will cause a very high load on the
server and the entire server will be sluggish, potentially affecting your sites
and service, until this sending process is completed. It is our job to keep the
server up and running without being sluggish or experiencing issues. Anyone who
causes the server’s load to go high will be suspended and the process will be
terminated. If you choose not to throttle, you will most likely be suspended
for crashing the server.
1. Any mailing list over 900 email addresses is
only allowed to be sent to during off-peak times to prevent high server loads.
Off peak times qualify as all day Saturday and Sunday, and 1AM – 8AM Eastern
Standard Time, Monday through Friday.
2. The list must be a Double Opt-In list. This
means a user has subscribed for a newsletter or other email marketing messages
by explicitly requesting it and confirming the email address to be their own.
Confirmation is usually done by responding to a notification/confirmation email
sent to the email address the end user specified. The double opt-in method
eliminates the chance of abuse where somebody submits someone else’s email
address without their knowledge and against their will. You will not be
permitted to mail any mailing list that you were given or purchased. In doing
so, this will also be considered spamming and may result in termination of the
Email Scripts must be able to handle and
document all information from a double opt-in list. This includes recording the
sign-up IP address and date/time, double opt-in verification IP address and
date/time, processing opt-outs (via web or email), and list removal on bounce
backs. All opt-outs or bounce back removals must be handled in a timely manner,
and outbound mail must be throttled on shared packages to a maximum of five
hundred (500) emails per hour. If your account is found to be using a script
that does not meet these requirements,GigaCloud Hosting reserves the
right to suspend, terminate, or deactivate your script or account.
3. Any unsolicited e-mail being sent will result
in suspension or termination of the offending account. We take a zero tolerance
stance against sending of unsolicited e-mail and other forms of spam.
4. Any mailling list MUST comply with all
guidelines set forth by the United States government. These can be found
5. No direct SMTP mailers are allowed. An example
of this would be a Darkmailer or The Bat!. Any mail should be sent through the
local mail server/MTA for further delivery by the server and not done directly
