------ Solution --------------------
There are not many 1000, of course. But direct sending is inevitably considered as spam.
You can change the ip address or the sender's email address.
------ Solution --------------------
Of course, there is also a sending interval.

Why must I use gmail?
------ Solution --------------------
Reference:
Reference: of course, there is still a sending interval.
Only one email address can be used for sending, and the IP address cannot be fixed. at most, there are 5 or 6 IP addresses for use. if there is a time interval, for example, 6 seconds, will it start with spam? Is there any other way?
This cannot be determined. Because you do not know the rules for defining spam in others' mailboxes.
For example, you have five ip addresses.
One ip address sends 200 ip addresses a day.
It takes about 24 hours/200 requests, about 10 requests per hour.

Group emails are easily blocked...

I tested it with phpmialer and sent emails continuously to the same mailbox. if there are more than three emails in outlook, they will enter the spam mailbox.
But in other mailboxes, such as enterprise qq, it will not be considered as spam!
------ Solution --------------------
Change your own data as much as possible
Ip address, source, version, time, and so on
------ Solution --------------------
I have used and cannot send so many messages consecutively, because some mailboxes will allow you to enter the verification code during sending. you must log on to the sender's mailbox and enter the verification code before sending the message. You can try to rent an email server to help you send it specially, but remember that the 1.1 mail server cannot let him send 1000 emails in a short time.
------ Solution --------------------
A gmail mailbox can send up to 150 emails a day.
