Connect the SendGrid sync and choose the list for referral emails

Create a SendGrid API key with Marketing access, connect it in GrowSurf, and select the list you want to keep updated. This guide works best for the documented SendGrid workflows where your automation or email send reads participant data from that synced list.

Choose the right primary CTA for the email

Use growsurf_share_url when you want the email to give the participant an instant share link. Use the GrowSurf referral portal URL pattern from the SendGrid tutorials when the message should send them back to their portal to track rewards, copy assets, or keep sharing:

• https://grow.surf/YOUR_CAMPAIGN_ID?grsf_email={{email}}
• If you use a custom referral portal domain, replace the https://grow.surf/YOUR_CAMPAIGN_ID base with your own portal URL.

Add live progress and reward context to the reminder email

For reminder-style emails, pair the main CTA with fields that answer the participant's next question right away:

• growsurf_total_referral_count shows current progress
• growsurf_next_milestone adds urgency when milestone rewards are enabled
• growsurf_referral_status can help explain why the participant is seeing the message now

Use lighter follow-up modules for nurture emails

The GrowSurf SendGrid tutorials include examples that add a compact referral module to an existing email, which is useful for onboarding drips or product-update sends where the referral CTA is important but not the whole message.

Send only after contacts finish updating and keep unsubscribe settings intact

SendGrid's current Marketing Campaigns guidance notes that contact updates can continue processing in the background. Wait for the list update to finish before you send. For ongoing reminder programs, keep your unsubscribe method configured in SendGrid as well so recipients can opt out without marking the email as spam.
