How it works

How to set up Microsoft SQL Server to Google Gmail in Weld.
Guided setup in 5 steps.

Full setup guide
  1. Step 01

    Connect your database

    Add Microsoft SQL Server as a data source in Weld with connection credentials that grant read access. Credentials are stored encrypted and never logged.

  2. Step 02

    Define your transformation

    Write a SQL query or dbt model that selects and transforms the data you want to push to Google Gmail. This is where you build audience segments, compute lead scores, aggregate metrics, or reshape data into the structure Google Gmail expects. You can preview results before activating.

  3. Step 03

    Connect Google Gmail

    Authenticate Google Gmail as a reverse ETL destination. Weld supports OAuth or API key authentication depending on the connector. Once connected, Weld automatically discovers the available objects and fields in Google Gmail.

  4. Step 04

    Map fields and configure sync

    Map your SQL columns to Google Gmail fields using Weld's visual mapper. Choose a sync mode: insert to create new records, update to modify existing ones, or upsert to do both. Then set a schedule from every 5 minutes to daily.

  5. Step 05

    Activate and monitor

    Enable the sync and monitor it from the Weld dashboard. Track record counts, sync duration, and error rates in real time. Configure Slack or email alerts so you're notified immediately if a sync fails or encounters data quality issues.

Use cases

Why sync Microsoft SQL Server to Google Gmail?
Act on warehouse data.

Push enriched segments and computed attributes from Microsoft SQL Server into Google Gmail to power personalized outreach and targeted campaigns.

Keep Google Gmail updated with the latest data from Microsoft SQL Server to automate workflows and reduce manual data entry.

  • Operationalize analytics

    Turn insights from your database into action by pushing model outputs and metrics into Google Gmail where your team works.

Data

What data can you sync?
From Microsoft SQL Server to Google Gmail.

Model the data in Microsoft SQL Server with SQL or dbt, then map it to objects in Google Gmail. Which objects you can write to depends on the Google Gmail connector and your account permissions.

    ELT

    ELT vs. reverse ETL: Microsoft SQL Server and Google Gmail

    ELT (Extract, Load, Transform) moves data from Google Gmail into Microsoft SQL Server for analytics. It's about centralizing data in your warehouse so analysts can query and join it with other sources.

    Reverse ETL does the opposite. It takes data that's already in Microsoft SQL Server and pushes it into Google Gmail so operational teams can act on it. This is the approach used on this page.

    Many teams use both: ELT to centralize data in the warehouse, and reverse ETL to activate that data back in business tools. Weld supports both directions between Microsoft SQL Server and Google Gmail.

    Sync modes
    Choose between insert, update, or upsert sync modes when pushing data to Google Gmail. Upsert is recommended to avoid duplicates.
    Rate limits
    Weld respects Google Gmail's API rate limits and automatically throttles requests to avoid hitting quotas.
    Data freshness
    Sync frequency depends on your Weld plan. Most connectors support schedules from every 5 minutes up to daily intervals.
    Security
    All data is encrypted in transit (TLS) and at rest. Weld is SOC 2 Type II compliant and supports IP whitelisting for database connections.
