It is recommended to use older gmail accounts that have been registered for more than six months to send emails.
Although the initial cost is higher, using aged accounts offers several advantages:

1. A higher chance of emails landing in the inbox.

2. As long as old accounts are not abused, they generally won’t get banned,
   so their lifespan is much longer. Under certain limits, you may be able to send emails for A long time, from 10 days to a very long time.

If you are using an aged account, it is recommended to follow the settings below to extend its usable time.
Otherwise, the account may be suspended by Gmail or require verification, resulting in being unable to send emails:

to: 1-1 cc:0-0 bcc: 10-40 Daily Limit: 280 Per Limit: 50
Alternatively, you can directly check "Auto control quantity".

Gmail old accounts may sometimes require phone verification after long-term use or logging in on a new computer.
Once verified, they usually remain usable for a long time. Since old accounts are costly and generally won’t get disabled easily,
Our software has integrated the APIs of some commonly used SMS verification service websites to extend their lifespan.

In addition, you can use your own registered or any gmail accounts obtained from other places.
