I’m a commodity trader (the non-technical side of this project) that built a web application that delivers auto-formatted and tailored product offerings to customers based on inventory scattered across the Eastern US. Im wondering if I can populate all the ‘Draft’ emails from my application into a table in my app and use the Gmail API to send one-by-one by pressing ‘Enter’ in quick succession and not have to worry about deliverability issues? When using an Email API provider they require an ‘Unsubscribe’ button and other rules as per Acceptable Use Policy. My customer base is about 500 people so Id rather sit at my desk and press ‘Enter’ 500x in quick succession rather than send in bulk via Email API with all the rules that basically show my hand that the offerings are automated to customers (would prefer it to look like I did it one-by-one).

Is there a way I can do this? Im thinking a table in my application whereby all the final drafts populate and can be sent via Gmail API. Or populate it into a ‘App Email Draft’ type of folder work email’s (Gmail), and figure out a way I can just bang Enter so they get sent one at a time and dont trigger spam filters or anything of that like.

My emails are all filtered to what the customer buys (SKUs) and WITH delivered pricing (freight API) so they are valuable because this is an industry still using phone-tag conversations all day to complete a transaction where I just cut through all the fat with my API-driven application. Think Uber -> Taxi except I’m internal software that does all the delivered pricing logic for me whereas most brokerages have a logistics department where you have to send a request and wait 15mins for the answer blah blah blah

I tried Email API but too many restrictions and can be at their whim and Id like to take that ambiguity out of workflow as the hope is to hire more traders. Would rather have all the drafts lined up so I can just press ‘Enter’ non-stop for 5mins and they all send invidually.
