Many outgoing emails are being caught in the recipients spam filter. How do I use SPF and DKIM to improve this situation

I have a client and recently they have been informed that a lot of the outgoing emails are being caught in the spam filter for many important recipients.

They use Exchang Online but all outgoing emails go via Mimecast after leavinf Exchange Online.

I want to configure DKIM and SPF correctly to try to minimise these outgoing emails going to spam.

Can someone explain how this should be done correclty.

Also do I need to configure DMARC too.

I have used MXToolbox to check if they are blacklisted and they are not.

I have little experience with any of the 3 things so could do with some advice.

1st of all add mime cast spf record as included lookup in your spf record
Then ask mime cast to generate dkim record for your domain and provide those details to you and then create dkim record in your public dns
Lastly you can create dmarc record once above both records are created
