What We DeliverWe execute the delivery-engine swap from LC Email to SendGrid while GoHighLevel keeps the funnels, CRM, checkout, SMS, and sequences.
Measures current sender health before any traffic moves from LC Email.
A cutover without a baseline can hide whether bounce, complaint, or reputation problems already existed.

"We compare 90-day bounce and complaint rates with Google Postmaster data before deciding whether the list needs validation."
Configures SendGrid Pro, a dedicated IP, and a fresh authenticated sending subdomain.
Poor DNS, sender, key, or tracking settings can damage trust before the dedicated IP has established a reputation.

"The fresh subdomain is authenticated through CNAME records, then verified in headers before GoHighLevel sends live mail."
Checks risky addresses and applies GoHighLevel DND settings and tags before cutover.
Invalid and risky contacts can raise bounce rates during warm-up and weaken the new dedicated IP.

"Addresses flagged by ZeroBounce or NeverBounce receive the matching DND setting and tag in GoHighLevel before sending begins."
Connects SendGrid as GoHighLevel's custom SMTP provider and verifies each email type.
A delivery-engine swap can break workflow emails, broadcasts, receipts, or appointment notices if each path is not tested.

Builds a Make.com scenario that returns SendGrid suppression events to GoHighLevel.
Bounces, blocks, and spam reports can remain in the CRM as sendable contacts unless both systems stay aligned.

Runs a three-week warm-up by engagement cohort with daily threshold checks.
Sending too much volume too early can harm the dedicated IP before it has a stable reputation.

"Higher-engagement cohorts send first, while daily bounce and complaint checks determine whether the next volume increase proceeds."
Sets weekly reporting, documents the build, and records monitoring and rollback steps.
Without shared reports and operating notes, delivery problems can go unseen and the team may not know how to respond.
