Sorry, but this is an awful suggestion IMO. As far as I know, Spark is not an e-mail client. Instead, they download all your e-mails and store them on their servers. Giving Spark and their technical provider Google full access to your mailbox pretty much destroys all safety and privacy advantages you have from owning a ProtonMail account.
