Hi Lena, following up on my note from last week. Would a 20 minute look be useful before your Q1 planning?

Sounds good. Could we talk Thursday? Afternoons work best for me.

Speed to lead, in one thread. A warm reply cools fast. AY Inbox notices it, sorts it and drafts the answer before you open it, so the meeting is booked while they still remember you.

An example of one reply's path, not a measured average.

Warm up before you send. Every new mailbox starts at 10 emails a day and adds one a day up to 40, trading real conversations with a pool of other mailboxes until providers trust it.

Answers that know your offer. Write your offer, tone and rules once. Remie drafts every reply from them and flags anything they do not back, like a discount you never set.

Campaign brain

Offer

Sourcing that finds engineers from their real work, for teams hiring five or more a quarter.

Tone

Plain and short. No hype, no exclamation marks.

Never

Promise prices or discounts in email.

Hi Ava, we work with hiring teams at a few companies your size. Happy to share how it went for them, and we can do 30% off this quarter.

Not in your brain: a 30% discount. Edit it before sending.

Everything has an API. Mailboxes, campaigns, contacts and replies are all an API key away, and your own agents can read the inbox and draft answers.

And the rest of the stack. Leads, research, CRM and deliverability live in the same workspace, so nothing gets copied between tools.

Lead finding and verificationFind people at the companies you name and add only the addresses that verify as deliverable.

Contact research and first linesRemie reads a lead's company and writes an opening line that is about them.

Lead scoring and signalsGrade every contact A to D against your ideal customer, and see which companies are hiring, raising or changing leaders.

CRM with pipelines and dealsReplies become deals, tasks and meetings without leaving the inbox.

Placement tests and an advisorTest where your mail lands and get told what to fix, mailbox by mailbox.

Sending domainsDNS checks for SPF, DKIM and DMARC, tracking domains and redirects in one place.

Forms and automationsCapture leads from your site and route them with steps that can read a reply and act.

IntegrationsSlack, HubSpot, Salesforce, Pipedrive, Apollo, Clay, Zapier, Make and n8n, plus webhooks.

Safe by default.

The limits that protect a sender's reputation are on before you change anything, and a mailbox that starts hurting other people is taken out of the warmup pool.

50 a dayCold emails per mailbox, out of the box
