> Hi, this can be the result of: not enough resources (you have a 1GB MEM server with 1 CPU and pay only like $20 for it) you DB doesn’t have index on email address in the leads table you have WAY TOO MANY columns in your csv you had an error and it stopped your cronjobs are not set or set wrong Here is an article to help you out: [How to import contacts to Mautic in the background without timing out - Knowledge Base](https://kb.mautic.org/article/how-to-import-contacts-to-mautic-in-the-background-without-timing-out.html)

If your resources are fine, then:

- check db index
- limit fields you import at once
- optimize cron
