GoHighLevel Setup Checklist: The 27 Settings to Configure in This Order (Before You Send Anything)

Most GoHighLevel problems that show up in month three were actually created in week one: a timezone nobody set, an email domain nobody authenticated, an A2P registration nobody finished. The platform has hundreds of settings, but 27 of them decide whether your CRM works or quietly fights you. This checklist puts them in the order they should be configured — foundations first, sending second, automations last — with what breaks if you skip each one.

Want this as a printable checklist? The free printable GoHighLevel setup checklist on our resources page covers the same 27 settings in a format you can tick off as you work. Get it by email and keep it next to your keyboard.

A. Account Basics

1. Business name, address, and contact details. Skip it and your emails, invoices, and booking pages carry incomplete or wrong business information — and your A2P registration can be rejected when these details don’t match your legal records.
2. Timezone and business hours. Skip it and every scheduled send, wait step, and appointment reminder runs on the wrong clock. This one forgotten setting causes more “the automation sent at 3 a.m.” stories than any other.
3. Users and roles. Skip it and everyone works from one admin login with full access to everything — no accountability, no permissions, and a security problem waiting to happen.
4. Company email and reply-to settings. Skip it and replies to your campaigns land in a mailbox nobody reads, so interested leads get silence.

B. Email Deliverability

5. A dedicated sending domain. Skip it and you send from a shared or default domain, which tanks deliverability and can put your main domain’s reputation at risk.
6. SPF record. Skip it and receiving servers can’t verify your mail is authorized — messages drift to spam or get rejected.
7. DKIM record. Skip it and your emails fail authentication checks that inboxes increasingly treat as mandatory for bulk senders.
8. DMARC record. Skip it and you have no protection against your domain being spoofed, and no reporting on who is sending as you.

C. Phone & SMS

9. LC-Phone / Twilio connection. Skip it and nothing phone-related works at all — no calls, no texts, no missed-call text-back.
10. A2P 10DLC registration. Skip it and US carriers block or heavily filter your business texts. Registration is not optional anymore; it is the price of sending.
11. A default sending number. Skip it and workflows send from an unexpected number — or fail silently — and customers see inconsistent caller IDs.
12. Voicemail and call settings. Skip it and missed calls dead-end instead of leaving a voicemail and triggering a text-back.

D. Pipelines & Stages

13. Your pipeline, built to match how you actually sell. Skip it and the CRM becomes a contact list with extra steps; a generic pipeline that doesn’t match your process gets abandoned within weeks.
14. Stage names that describe real milestones. Skip it and your team can’t tell at a glance where a deal stands, and stage-based automation fires at the wrong moments.
15. Lost reasons and opportunity defaults. Skip it and you lose the data that tells you why deals die — the most useful reporting a small business can have.
16. Core contact custom fields. Skip it and the details your automations need — service requested, source, appointment type — live in notes nobody can trigger on.

E. Calendars & Booking Rules

17. Your calendars, one per bookable service or person. Skip it and customers book the wrong thing, with the wrong person, for the wrong duration.
18. Availability, buffers, and booking windows. Skip it and you get back-to-back bookings with no travel or prep time, and appointments booked impossibly far ahead or five minutes from now.
19. Confirmation and reminder settings. Skip it and no-shows climb, because the customer got one email at booking and nothing since.
20. Calendar sync with your real calendar. Skip it and GoHighLevel happily double-books you over personal appointments it cannot see.

F. Day-One Automations

21. Missed-call text-back. Skip it and every missed call is a lead talking to your competitor instead — this is the highest-value automation in the platform.
22. New-lead instant reply. Skip it and web leads wait hours for a first response, by which time most have contacted someone else.
23. Review request after the job is done. Skip it and reviews depend on someone remembering to ask, which means they mostly don’t happen.

G. The Final End-to-End Test

24. Submit every form as a customer would. Skip it and you discover the broken trigger, wrong pipeline, or missing notification from a real lead instead of a test.
25. Book a test appointment through your own booking page. Skip it and you never see the double-booking, the wrong timezone on the confirmation, or the reminder that never fires.
26. Send a test text and email to your own phone and inbox. Skip it and deliverability problems — spam folders, filtered texts — stay invisible until they cost you enquiries.
27. Trace one test contact through everything. Open the contact and follow their timeline: form, pipeline, messages, booking. Skip it and the gaps between the systems stay hidden, because each part looked fine on its own.

What Not to Touch Yet

Resist two day-one temptations. Don’t build thirty workflows before the basics above are proven — every workflow built on unset foundations inherits their problems. And don’t import your entire old contact list on day one: clean it first, remove dead addresses and numbers, confirm your sending setup is fully authenticated, and import in small stages, or you will damage your email and SMS reputation before you’ve sent anything that matters.

Where DIY Setups Usually Fail

Five settings account for most of the cleanup work we see: A2P registration left half-finished, DKIM/DMARC never added, the account timezone left on default, calendar conflicts from an unsynced personal calendar, and workflow re-entry settings that stop automations firing twice for returning leads. If you are setting up yourself, double-check those five before anything else. This checklist is the order our own setup and implementation work follows on every build, precisely because skipping steps is what makes setups expensive later. If you’d rather hand the whole sequence to someone who does it daily, book a call and we’ll scope your setup on the call.
