The Onessta and Email SMTP integration connects Onessta to Email SMTP through eGrow's no-code automation engine. You build a workflow once — pick a trigger from Onessta, choose an action in Email SMTP, map the fields — and eGrow keeps both apps in sync from then on, in real time, with no developers required.
Common things teams automate between Onessta and Email SMTP: sync new Onessta records into Email SMTP, push Email SMTP updates back to Onessta, fan out one event in Onessta into multiple actions across Email SMTP, alert your team in chat when something breaks, and unify customer data so both systems see the same source of truth.
Setup takes about 5 minutes. Sign up for eGrow, authorise Onessta, authorise Email SMTP, drag-and-drop a workflow between them and turn it on. Free white-glove onboarding is included with every plan — a real account manager will build your first workflow with you over a screen-share.
