Can I stagger mass emails ? Having mail issues

I run a car club and I need to be able to mass email my members.

My ip sometimes gets blocked with mass emails and also certain providers don't allow our emails for notifications from the site . I don't send out too many email blasts maybe 4 a month and we only 1300 users.
Is there a way to send out 1 at a time ?
Is there any way to ensure my members get forum emails

I've looked into different options , don't really understand why I'm on the list all our emails go to registered members. Unless its a spammer that cause the flags on us. We did have some hacker issues when we still had vb

Is a mailchimp type of service worth it ? Is there a service like that that could be integrated into our forum ?

Any help is greatly appreciated

What mail send method are you using now? To a local SMTP server on your server that you can control? If so, most(all?) SMTP servers have send rate limiting functionality.
