What this does
When a new signup comes in, Twain researches the person and their company in real time and writes a welcome message in your brand voice, built around a genuine detail about that specific signup rather than a merged first name. The message is saved as a draft, it is never sent automatically.
Why it helps
A signup is the warmest a lead will ever be, but a great welcome takes 15 to 20 minutes of research per person, so most teams fall back on a generic autoresponder. Twain drafts a researched welcome in about 20 seconds, so every signup gets a considered first touch whether you get one a day or a hundred.
Where the draft lands
A draft in Gmail, ready to open, review, and send.
A summary card in Slack with who signed up, the subject line, and the full draft text, plus a link into Twain.
Nothing goes out until a person reads it and hits send.
Where the voice comes from
The writing style comes from the Agent and campaign you set up once in Twain, so drafts sound consistent across every signup, not like a generic AI model.
When it can't personalize a signup
The workflow is honest about its edges instead of guessing. If a signup has no work email and no LinkedIn profile to research, or if a draft can't be saved to Gmail, it tells you plainly in Slack rather than sending or pretending, so you never trust a draft that isn't really there. If you connect an optional LinkedIn lookup provider, it can resolve a LinkedIn profile from a personal email and still write the welcome.
Optional: a LinkedIn welcome
If a signup only has a LinkedIn profile and no work email, the workflow can hand the message off for you to send on LinkedIn, or push it into a dedicated LinkedIn sender like HeyReach. That branch ships turned off, so you enable it deliberately. See Connect Twain to HeyReach for how the HeyReach integration works.
Cost
