Hello @JordanJ040 ,
If you do a particularly large sendout to contacts, our system does that automatically. If you're wanting to do it manually in much smaller chunks, then you'd need to set up the smaller segments / lists and just do manual resends for each subsequent one after the first.
Here are some general best practices for deliverability.
Deliverability can have a lot of variables, from elements on our side, on your side, on the recipient's side, and in their email system company's side. It's also a generally good idea to set up additional authentication for your emails - whether that's through us if you have a free domain (e.g. Gmail, Yahoo, AOL, etc.) or via self-authentication if you have your own domain (such as through a business or other organization).
If you'd like to learn more about safelisting, and what it entails:
Safelisting domains in a security system
Safelisting email addresses in an email client or security system
If you're wanting more in-depth, specialized insight on your current deliverability, it'd be worth speaking with one of our Deliverability agents.
