Read our Privacy PolicyThree steps, two minutes. By the end you'll have your first AI column written into a real sheet. From there, chain verify, scrape, and AI into one pipeline.
Open any spreadsheet, or start a new one with the data you want to enrich. The ReplyLabs sidebar lives inside Google™ Sheets, not in a separate app.
Inside your sheet, click the menu path below. The sidebar opens on the right. The first time, it asks you to sign in. Use Google™ or email, whichever you prefer.
Extensions → ReplyLabs → Open sidebar$20 in free credit lands on your account at signup. Roughly 2,000 verified emails, or about 2,000 to 7,000 AI-personalized rows depending on the model (GPT-4o mini and Claude 3.5 Haiku stretch the furthest).
In the sidebar, write a prompt that references one of your columns (for example, {{company}} to pull each row's company name). Pick the column to write the result into. Click Run. Results stream in row by row.
Write a 1-line opener for a cold email to {{first_name}} at {{company}}.
Mention something specific about their industry.Start with 5 rows in test mode to dial in your prompt before running on hundreds.
Or skip ahead: try a pipeline
Instead of one prompt, run a template that chains verify, scrape, and multiple AI steps in one click. ICP Enrichment is a good first taste.
Read the workflows guideBeyond your first prompt, the sidebar covers the full enrichment loop. Same sheet, no new tools.
Run any LLM (OpenAI, Anthropic, Google™ Gemini, Mistral) across thousands of rows. Reference cell values with {{column_name}} syntax. Personalized cold emails, summaries, classifications, anything text-based.
Write a personalized 1-line opener for {{first_name}}
at {{company}}. Reference their {{industry}} sector.Drop URLs into a column. Scrapes run inside your Apps Script (Google IPs, not datacenter), so LinkedIn /company/ pages and corporate sites mostly don't block. From $0.005 per URL. Feed results into the next AI prompt.
Run every email in your sheet through No2Bounce and get back deliverable, risky, or undeliverable. $0.01 per email on Pro. Bring your own provider key on Scale and pay raw provider rates.
What we learned across thousands of prompts. Skim these before your first run.
"Write a cold email opener" beats "write a cold email." Specific prompts get specific outputs.
Use {{column_name}} to pull values from your sheet. ReplyLabs reads your header row automatically.
Test mode runs your prompt on the first 5 rows. Iterate on those before running 500.
Cheaper models (GPT-4o mini, Claude Haiku) are great for short, structured outputs. Reach for GPT-4o or Claude Sonnet when nuance matters.
Tell the model who it is and how to behave. "You are a B2B sales rep writing in a casual tone" before the actual prompt body.
Cost per row shows in the sidebar before you run. Top up your balance when it gets close to zero.
