How to Resend an SMS Blast to Non-Responders in GoHighLevel

If you want to resend an SMS blast to non-responders in GoHighLevel, the hard part is not the second send. It's building an accurate list of the people who got the first text and never answered. This guide shows how to do that with native tags, workflows and smart lists, what to check before you hit send again, and where the manual way starts to cost real time.

Why GoHighLevel doesn't hand you a non-responder list

When you send a bulk SMS from Contacts, the job shows up under Contacts > Bulk Actions. As of October 2026, its stats window shows totals like attempted, sent and skipped, and the sent view breaks down into delivered, clicked and failed. You can download a CSV for each of those groups.

There is no "replied" or "didn't reply" group. HighLevel tracks replies inside each contact's conversation, not against the bulk action that triggered them. So the list you actually want, "got this blast and never wrote back," has to be built.

There are two native ways to do it. One works if you set it up before the blast. The other works after the fact, with more manual effort.

Method 1: Resend an SMS blast to non-responders with tags and a workflow

This is the cleanest native approach. It takes about ten minutes the first time and can be reused for every blast.

Step 1: Tag everyone who will receive the blast

1. Go to Contacts > Smart Lists and filter to the audience you're about to text.
2. Select all contacts in the list.
3. Use the bulk Add Tag action to add a dated tag, for example blast-2026-10-14.

That tag is your record of who was in the send. Don't reuse it for the next blast.

Step 2: Build a workflow that tags anyone who replies

1. Go to Automations > Workflows and create a new workflow.
2. Add the Customer Replied trigger. Limit it to the channels you care about, such as SMS.
3. Add a filter or If/Else so the workflow only continues when the contact has the blast-2026-10-14 tag.
4. Add an Add Tag action that applies replied-2026-10-14.
5. Publish the workflow before you send the blast.

Step 3: Send the blast

Send your bulk SMS to the same smart list. For large lists, use Send in Drip Mode so messages go out in batches. Drip mode lets you set a batch quantity, a repeat interval and allowed sending hours, which helps with carrier filtering.

Step 4: Build the resend list

After your reply window (24 to 72 hours is common), build a smart list with these filters:

• Tag is blast-2026-10-14
• Tag is not replied-2026-10-14
• DND for SMS is not enabled

Save it as a smart list, review a sample of contacts by hand, then send your follow-up from there.

The workflow-only alternative

If you send through a workflow instead of a bulk action, you can skip the extra reply workflow. Add a Wait step right after the Send SMS action, set it to wait for a contact reply, and turn on the timeout. Contacts who time out go down the "no reply" path, where you can tag them or send the follow-up directly. HighLevel notes that the Wait step should sit directly after the message it's watching.

Method 2: Build the list after the blast already went out

If the blast is already sent and nothing was set up, you can still get close.

1. Open Contacts > Bulk Actions, find the blast, open its stats and download the Delivered CSV.
2. Open Conversations and use the filter for Last Message Direction set to Outbound, plus Last Message Channel set to SMS. As of October 2026, those filters exist in Conversations but not in contact smart lists.
3. Compare the two lists in a spreadsheet. Contacts who were delivered the blast and whose last message is still your outbound text are likely non-responders.
4. Import the result, or tag those contacts in bulk, and build your smart list.

This works, but it has gaps:

• Last message isn't the whole story. If a contact replied and then got an automated message from you, their last message is outbound again and they look like a non-responder.
• Other channels get missed. Someone who called back or answered by email still looks silent in an SMS-only view.
• It's slow. Matching CSVs by phone number for a few thousand contacts is an afternoon, and it has to be redone for every blast.

Before you resend: a short compliance check

A second text to someone who ignored the first is where a lot of complaints and carrier filtering come from. Run through this every time.

• Consent. Only text people who opted in to receive messages from this business. A resend doesn't change that.
• Opt-outs and DND. Exclude anyone marked DND for SMS. If someone replied STOP after the first blast, they must not get the second one. Check that your filter catches this.
• A2P 10DLC. Your registered campaign use case and sample messages should match what you're sending. Promotional resends on a campaign registered for something else can get filtered.
• Change the copy. Sending the identical text twice reads as spam to both people and carriers. Rewrite the message and keep the opt-out language.
• Space it out. One resend, a few days later, inside normal hours. Use drip mode for large lists.

None of this is legal advice. If you're in a regulated industry, check the rules that apply to you.

Where the native way gets slow

The tag-and-workflow method is accurate when you remember to set it up. In practice, agencies run blasts across many sub-accounts, and someone forgets the reply workflow, reuses a tag, or sends from a different list than the one they tagged. Then you're back to Method 2 and a spreadsheet.

The "last message direction" check is also weaker than it looks. A conversation that ends on your text isn't proof the contact never answered. They may have replied, then received your automated follow-up. They may have called. The only reliable answer comes from reading each contact's full history since the blast, which is what you can't do by hand at scale.

How Blast Follow-Up handles it

Blast Follow-Up from RGS Tools builds the resend list without any setup before the blast.

• Blast finder looks at what was actually sent and groups texts sent close together into blasts. You don't need campaign IDs or workflow changes.
• No-reply checker reads each contact's real history and drops anyone who texted, called, emailed or chatted back. You choose strict (leave out anyone who ever replied) or lenient (only leave out people who replied since this blast).
• Resend tagger adds a dated tag like no-reply-oct-14 to everyone left. Filter by it in Contacts, review, and send your follow-up from HighLevel.
• Automatic daily runs let you set a time and timezone per sub-account so every new blast gets tagged once, on its own.

Blast Follow-Up never sends messages. It only adds a tag, so the resend, and the compliance check above, stay in your hands. It's $39/mo per agency with unlimited sub-accounts and a 7-day free trial.
