Prerequisites
- An active No2Bounce account with access to Email Validations > Integrations
- A SendGrid account with API access enabled
- Your SendGrid API Key (SendGrid dashboard > Settings > API Keys): no separate API URL required
- Sufficient credit balance: validation costs 1 credit per record
Step 1: Go to Integrations & Click Connect on SendGrid
Log in to your No2Bounce account. In the left sidebar, click Email Validations, then open the Integrations tab.
You'll see your other connected tools alongside SendGrid, which shows a Connect button. Click it to begin the setup.
Step 2: Review What the Connection Enables
A panel opens outlining what connecting SendGrid allows No2Bounce to do: access your email lists to verify and clean records, synchronize verified lists back to improve deliverability, monitor deliverability metrics, integrate validation results with your SendGrid campaigns in real time, and view live verification stats.
Click Allow Access to continue.
Step 3: Enter Your SendGrid API Key
Unlike some other integrations, SendGrid connects with a single API Key, with no separate API URL or OAuth exchange needed. Find your key in the SendGrid dashboard under Settings > API Keys, paste it into the field, and click Next.
The API Key is the only credential SendGrid requires. There's no separate endpoint URL to configure.
Step 4: SendGrid Is Now Connected
Once your key is accepted, you're returned to the Integrations dashboard. The SendGrid card now shows a green CONNECTED badge, and a Manage Connection option appears so you can review or disconnect it at any time.
Step 5: Select Your List & Choose Columns
On the SendGrid Integration page, choose the contact list you want to work with from the tabs at the top. Under Choose Columns, select which fields to import: Email, First Name, Last Name, and Phone are all available. Then click Load Data to preview your records.
The Email column must always be selected: it is required for the validation process to run correctly.
Step 6: Select Records & Click Validate Now
Your contacts load into a table. Use Select All, Clear Selection, Custom Select, or the batch selection slider to choose exactly which records you want to validate. Once you're happy with the selection, click Validate Now.
Step 7: Set Your Validation Preferences
The Validation Preferences dialog asks you to confirm which column holds the email address (Validation Field), and lets you map an optional Score Field. It previews the records you've selected and shows how many credits the run will use before you commit.
Credit usage: credits are debited based on the number of email addresses processed. Each email consumes 1 credit. Runs are capped at 100,000 records.
Step 8: Watch Your Validation Progress
After starting validation, a circular progress indicator tracks completion in real time. The Validation History table below logs every run, including ones still in progress, with date, source, record counts, and status.
Step 9: Review Results & Export
Once a run reaches 100%, results are broken down into Deliverable, Risky, and Undeliverable. From Validation History, use Export Options to download all emails, deliverable only, or undeliverable only. Downloads stay available for 7 days after each run.
Understanding Your Results
Every validated email is sorted into one of three categories, shown as a live percentage breakdown on the Validation Progress page:
- Deliverable: valid, safe to send
- Risky: catch-all or uncertain; send with caution
- Undeliverable: invalid, do not send
