Cold DMs with a 60%+ reply rate.

Cold DM campaigns on X get replies when the lead has seen your name before the message lands, and when it lands while they are around. That is how Nico AI runs every Gemlead campaign. He warms each lead up with a like, a comment on their post and a follow, Radar waits until they are active on X, and the DM written for them follows. One follow-up three days later, then a Cleaner removes the public traces. Our DMs average a 60%+ reply rate, while the largest cold email studies put the average cold message at 3 to 5%.

Why most cold DMs on X get ignored

A DM from a stranger starts behind. If the lead does not follow you, it lands in their Requests, not their inbox (X Help Center), next to every other unsolicited pitch, from a name they have never seen.

Then the message usually does the rest:

• Generic loses. 73% of B2B buyers actively avoid suppliers who send irrelevant outreach, in a Gartner survey of 632 buyers. 48% of decision makers blame generic, impersonal messaging when cold emails fail, in Hunter's State of Email Outreach 2026.
• AI that sounds like AI loses. In the same report, 69% of decision makers say it bothers them if AI was used, unless the output feels genuinely human.
• The baseline is low. Hunter's 31 million cold emails averaged 4.5% replies per sequence, 3% for sales. Instantly's 2026 benchmark puts the average at 3.43%.

No large public study measures X DMs on their own, so these figures come from cold email, the closest equivalent. X adds its own rules: its authenticity policy lists bulk, aggressive unsolicited DMs and identical DMs as platform manipulation. On X, a campaign has to send one message per person, at a human pace.

How a warm-up campaign runs in Gemlead

One campaign per persona and prospecting method

Click Create campaign, pick the prospecting method, then start from its template or a Blank campaign. A campaign writes only to the leads its method finds, with the steps that suit how they were found. You can run several campaigns on the same persona to test copy, and edit every step, delay and message before you start.

The Warm-up flow, step by step

The Warm-up flow is the template for Lookalike network leads, who do not know you yet. It is built for reply rate:

1. Radar. Nico AI adds the lead to your sending account's private X list and waits until they are online. The first touches land while they are there, on the post they just published.
2. Like and comment. He likes their post and comments on it, with a comment written for that post.
3. Follow, an hour later. Many people check who followed them.
4. Inbox opened test, six hours later. If their DMs are open, an Interaction test checks whether they reacted. Those who did get a warmer DM. Those who did not get a cold DM, plus a bridge comment saying a message is waiting in their requests. If their DMs are closed, a comment invites them to write.
5. Follow-up DM, three days later, if they have not replied.
6. Cleaner. If they never converted, Nico AI can unfollow them and remove this flow's likes and comments, as you choose. Your DMs are never touched.

Each DM is written from the lead's profile, recent posts and your persona, as explained on personalized DMs. You can also write a fixed message yourself.

Instant flows, for leads found in the moment

Keyword search, Competitor followers and Competitor comments find people by something they just did: a post, a follow, a reply. Their Instant flow skips Radar. The first touches go as soon as the lead enters: a like and a follow, plus a reply on their post for Keyword search. A day later comes the message. The newest leads enter first, and the DM mentions their post in one sentence while it is under 3 days old. For Competitor followers, the DM never says they followed a competitor.

Timing: Radar and the Contact window

Timers are minimums. After a timer, a like, comment, follow or DM also waits for the lead's Contact window: the hours Dana AI found they are usually online, in their own timezone. If a step is postponed three times, Nico AI sends it anyway, so no lead waits forever.

When they reply, Nico AI stops

A reply ends the sequence for that lead. The conversation lands in your DM inbox, synced with X, where you or Sam AI take it from there.

Why warming up works

Each step of the flow answers something the data says about cold outreach:

• Personal beats bulk. Emails with two personalized fields got 56% more replies than generic ones, 5.6% against 3.6%, and 67% of decision makers say personalization using publicly available information makes them more likely to reply (Hunter, 2026). LinkedIn InMails sent one by one got roughly 15% more responses than InMails sent in bulk (LinkedIn).
• Timing matters. In a Harvard Business Review study of 1.25 million leads, companies that tried to reach a lead within an hour were nearly seven times as likely to qualify it as those that waited longer. On LinkedIn, 65% of InMail responses arrive within 24 hours.
• One follow-up, not five. 58% of all replies came from the first message in Instantly's benchmark. In Hunter's data, three messages more than doubled total replies, 6.8% against 3.3%, while three or more follow-ups lowered the average. Backlinko's study found a single follow-up brought 65.8% more replies.
• A human pace. Email accounts sending 20 to 49 emails a day got reply rates 27% above the average, 5.7% against 4.5% (Hunter, 2026). Your campaign's daily leads limit sets that pace for each X account.

On X, the follow, the like and the comment add what email cannot: they reach the lead's notifications before your DM does. The writing rules behind each message, with templates, are in how to write cold DMs on X that get replies.

Manual cold DMs vs a Nico AI campaign

Who it is for

• B2B founders. Lookalike network with the Warm-up flow: founders and operators who match your buyer, warmed up before your DM arrives.
• Agencies. One campaign per client persona, and a second campaign on the same persona to test which opener gets more replies.
• Coaches and info products. Keyword search with its Instant flow: the person who just posted the struggle gets a like and a reply within minutes, and your message the next day.
• B2C sellers. A sports betting tipster or a creator runs Competitor comments: people replying to a rival get a like and a follow at once, and a message a day later.

Best practices for DM campaigns on X

• Keep the daily limit under your X cap. X caps how many message requests one account can send in 24 hours, and a paid X plan raises that cap. A campaign's Daily leads limit starts at 75 and goes from 5 to 800: keep it at or under your account's cap. People who already follow you or chat with you do not count.
• Start from the template. Change one thing at a time, and test a new opener in a second campaign on the same persona.
• Give Sam AI an objective. In the campaign settings, choose what a reply should lead to: a sale, a call, another channel, or qualify then hand over. Then his pace: Relationship, Balanced or Direct.
• Read the first DMs. Check tone and facts before you raise the volume, as any AI SDR setup should.
• Fix your profile. A lead who gets a follow, a comment and a DM opens your profile next. Say what you do and for whom.
