Google Sheets & Gmail Follow-up Automation

A team needs to know who has received an email, which follow-up is due and whether someone has already replied. Keeping the lead list in a spreadsheet is familiar, but manually checking every thread and due date creates repeated work. The automation needs to preserve a readable record and stop a sequence when a real conversation begins.

Google Sheets holds the lead data and campaign status, while Gmail sends personalised messages from the connected account. The sequence can send an initial message and later follow-ups in the same email thread. Reply detection marks the lead as replied and stops the remaining scheduled steps.

The four-stage flow is lead entry in Sheets, Gmail sending, scheduled follow-up stages and reply cut-off. Fields can include the person’s name, email, company, a custom note and the current stage. A schedule such as days 2, 4 and 7 is an example; the actual cadence is configurable for the agreed package and workflow.

• Variable-based email personalisation using the lead’s Google Sheets fields.
• Initial outreach and scheduled follow-up stages through the connected Gmail account.
• Same-thread follow-ups and professional HTML templates where included in the setup.
• Reply detection, automatic sequence stop and a visible Replied status.
• Timestamps, lead status and the next scheduled stage recorded in Sheets.
• Campaign-specific templates, sending-day/time settings and segmentation where configured.
• Testing, client approval, onboarding and team handover.

Setup options

The Starter scope covers a single sending account, a standard template and up to two follow-up stages. Professional adds up to three stages, HTML-template support, campaign personalisation and configurable timing. Business covers additional templates, multiple sequences and custom campaign rules. High-volume or multi-mailbox work is scoped separately with controlled batching, sending infrastructure and provider limits.

Where it fits

The workflow can support travel enquiries, property enquiries, recruitment follow-ups, agency proposals, consulting conversations and B2B customer follow-up. The agreed setup defines the sending accounts, campaigns, templates, integrations and support. Google Workspace, paid APIs, sending-provider fees, domains and purchased contact data are separate from the automation setup.

Request an email automation walkthrough to review the working process in a screen-share session.

1. Review sample lead rows and the personalisation fields in Google Sheets.
2. Inspect an email template and the configured follow-up schedule.
3. Follow a demonstration message and its later stages in the same Gmail thread.
4. Reply to the test thread during the walkthrough and check that the record changes to Replied and later follow-ups stop.
5. Review status timestamps, campaign settings and the handover needed for your own accounts.

Use sample contacts and a test mailbox for the demonstration. Production sending capacity and email delivery depend on the provider, account limits, domain reputation and recipient data; replies or inbox placement are not guaranteed.
