First, make sure your aliases are linked to your primary FollowUpThen account..
Then, head to your connected services page. If multiple emails are aliases to one inbox, only connect that one inbox. This is regardless of how many aliases point to it. Don’t connect aliases.
Not sure of what is pointing where? Login to (what you suspect) is your primary inbox. Send an email to each of your aliases and see if you’re getting the emails. If one does not arrive, connect that inbox to Context.io separately.
