How Warmerly does it
Warmerly, in detail.
Two LinkedIn campaign steps (a connection request and a message) sit in the same sequence as email, and a separate warmup runs five kinds of activity. It costs $19 a month for each connected account, with no trial.
01
Price and how it is bought
LinkedIn is sold on its own, not inside the email plans. One connected account is $19 a month. A pack of 3 accounts is $49 a month and a pack of 5 is $75. It is charged straight away, there is no trial, and LinkedIn accounts are not refunded. You can cancel and keep access to the end of the paid period.

02
Two steps in a campaign
A campaign sequence can hold a LinkedIn connection step, a LinkedIn message step, wait steps and email steps. A ready-made 'LinkedIn then email' template connects first, waits 2 days, then sends two emails. The list editor handles these linear steps; only the canvas editor builds branches.

03
Messages wait for the connection
LinkedIn only lets you message first-degree connections. Before a message step the engine looks at the lead's profile. If the invitation is still pending it re-checks every 6 hours without spending send budget, and it skips the lead if they are still not connected 21 days after the invitation.

One shared daily budget
A standard account is capped at 10 invitations a day and 50 a week (premium: 20 and 100). The other mature daily caps are 50 messages, 40 profile views, 20 reactions, 5 comments and 2 posts. Warmup and campaigns spend from the same budget. You can set lower caps, never higher.

Where Warmerly is behind
We found no code for InMail, skill endorsements, following profiles, liking posts as a campaign step, or visiting a profile as a step. There is no LinkedIn webhook, tag or transfer step in a sequence.

Replies from LinkedIn land in the same inbox as email
LinkedIn replies to campaigns are labelled by reply label, with interested, question and referral counting as leads, and stop that lead's sequence.

AI writes each LinkedIn message from the profile
An optional step writes each LinkedIn message for one prospect from their Linkup profile and the campaign brief, stores it so a preview is what is sent, and costs 1 AI credit per message.

A/B testing is listed

Profile engagement is its own feature
Visit, follow, like the latest post and endorse can run on their own or inside a drip campaign. Visiting a profile triggers LinkedIn's own view notification to its owner.

What Dux-Soup does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- Conditions other than a reply stopping the sequence
- A library of ready-made sequences
- A ramp-up schedule for a new LinkedIn account
- Whether AI qualification sends replies without a person checking
- What data goes to ChatGPT, Claude or Gemini

In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
If you need endorsements, follows or InMails, Warmerly cannot do them
Its LinkedIn steps are a connection request and a message.
If LinkedIn is one step of an email sequence, the add-on may be enough
Connection requests and messages sit in the same sequence as email.
Compare by what you will actually send
Count the actions your sequence uses before comparing prices.
Warm a prospect before asking
Dux-Soup can visit, like their latest post and endorse a skill before it sends a connection request, which its page says warms people up. On Warmerly a campaign starts with the connection request itself, with the 10 a day ceiling in view.
A week of connection requests
At Warmerly's full ramp a standard account sends 10 requests a day and up to 50 a week, so a five-day week uses all 50 (our arithmetic). Dux-Soup defaults to 20 a day, which is 100 over five days, and it tells beginners to start at 5 to 10.
Reaching someone you are not connected to
Warmerly can only message a first-degree connection and waits up to 21 days for an invitation to be accepted. Dux-Soup can send an InMail, or a free message to an Open Profile member on Sales Navigator.
Testing two openers
On Dux-Soup you can split an audience and compare acceptance for two versions. On Warmerly you would build two campaigns by hand and compare their results yourself.
