Does SendGrid verify emails?

SendGrid offers an Email Validation API as a paid add-on, but it is priced separately from your SendGrid plan. Truelist provides standalone verification that works regardless of your SendGrid plan level.

How do I export contacts from SendGrid?

Navigate to Marketing > Contacts, select your list or use All Contacts, click the Actions dropdown, and choose Export CSV.

Can bad marketing emails affect my SendGrid transactional delivery?

Yes. SendGrid uses shared infrastructure for both. High bounce rates from marketing campaigns can lower your overall sender score and impact transactional email delivery.

Is Truelist cheaper than SendGrid Email Validation?

Truelist typically offers lower per-email pricing than SendGrid's validation add-on, and you do not need to be on a specific SendGrid plan tier to use it.

SendGrid (by Twilio) is an email delivery platform used for both transactional and marketing email, providing APIs, SMTP relay, and a visual marketing campaigns editor.

Why verify your SendGrid email list

SendGrid handles high-volume transactional and marketing email, and your sender reputation is shared across both types. Invalid addresses in your marketing lists generate bounces that can degrade your transactional email delivery. For API senders processing large volumes, even a small percentage of bad emails compounds into serious deliverability damage.

shield Protect Transactional Delivery: SendGrid shares sender reputation across email types. Clean marketing lists prevent bounces from affecting password resets, receipts, and notifications.
savings Reduce Per-Email Costs: SendGrid charges by email volume. Eliminating sends to invalid addresses directly reduces your monthly bill.
settings Clean API Contact Data: If you send programmatically via the SendGrid API, verify addresses before they enter your pipeline to prevent bounce-related reputation damage at scale.
analytics Accurate Delivery Metrics: Invalid emails inflate your bounce rate in SendGrid analytics. Clean data gives you a true picture of your delivery performance.
