As answered by people managing Instantly.ai and RowTrigger.
RowTrigger's answer:
Google Sheets, Google Apps Script, Gmail, and Google Workspace.
RowTrigger's answer:
RowTrigger automates personalized email campaigns directly from Google Sheets using your own Gmail or Google Workspace account. It combines initial sends, follow-ups, fresh resends to non-openers, unique email variations, and automatic stops for replies, bounces, and unsubscribes.
RowTrigger's answer:
RowTrigger is built for people who already manage their leads in Google Sheets and want email automation without moving their data to another platform. Your campaigns run from your own Gmail or Google Workspace account, while your contacts, campaigns, and results stay in your Google account.
RowTrigger's answer:
Sales teams, lead generation professionals, recruiters, agencies, freelancers, founders, and anyone who uses Google Sheets for email outreach and wants to automate personalized campaigns and follow-ups.
RowTrigger's answer:
RowTrigger was created to make email automation easier for people who already manage their outreach in Google Sheets. Instead of moving leads into a separate platform, RowTrigger brings automated sending, follow-ups, resends, and campaign controls directly into the workflow they already use.
RowTrigger's answer:
RowTrigger is currently in beta and does not have publicly named customers yet.

I rebuilt my outreach this week after my reply rate tanked from 4% to <1%. Pulled fresh data from 5+ deliverability blogs (Autobound, MarketingProfs, HyperGen, Instantly), built a Python validator to enforce the new rules across 70+... - Source: dev.to / 5 months ago

Anywho, the old mailgun system was able to send emails immediately + had images in them. The recommendations we got were to remove ALL images, and instantly.ai has to delay a few minutes between email. So the emails get out slower and no... Source: about 3 years ago
