When a cron job triggers a send, Interspire Email Marketer will look to see what contacts are due to be sent the autoresponder or email campaign, then it will check to
see which of those contacts meet your filtering requirements.
So in short, yes, if you change details after sign up and they then
qualify for the autoresponder when it is due to be sent then they will
receive it.
If however if they did already qualify for the autoresponder or email campaign and they change their details and then become invalid at the time of the send they will not be sent it.
