Dripline

Cold email that waters, not floods.

A smart sprinkler waters one zone at a time, on a schedule, and skips the day it rained. Dripline sends a small firm's outreach the same way, and anyone who has already replied has had their rain. Below is Marcus's November, already run. Turn the dial to change it.

A lawn in four zones, one sprinkler head for each address

Zones

Marcus Hale Bookkeeping

Each list of people you write to is a zone on the lawn. Tap one to see where it is; switch it off to leave it dry this month.

The dial is the whole menu, like the one knob on the garage controller. Turn it, or press the knob.

Setup

About ten minutes, once

  1. Connect your inbox

    Sign in with Google or Microsoft. Dripline sends through your own account, so every email comes from you@yourfirm.com, sits in your Sent folder, and replies arrive in your inbox with the rest of your mail. It never sees your password.

  2. Soil test

    Before the first run it reads three records on your domain that mail providers check to decide whether you are really you. Anything missing comes with the one line to paste at your domain host.

    SPF who may send for youDKIM a signature on each emailDMARC missing, one line to add

  3. Lay out your zones

    Paste addresses or upload a spreadsheet. Each address is checked before anything is sent, and the ones that would bounce are marked as frozen ground and left alone.

  4. Set the schedule, then run

    Up to four emails per person, written by you. Rain skip is on from the start: replies, weekends, holidays and bounces.

Warm-up and deliverability

New sod gets a little water, often. A new inbox needs the same. Mail providers trust an address that has sent a steady, human amount for weeks, so Dripline starts a new inbox at 10 emails a day and adds 5 a week up to 40.

40 a day: the ceiling 10wk 115wk 220wk 325wk 430wk 535wk 640wk 740wk 8

Each email goes out a few minutes after the last, in plain text, on weekdays between 8 and 5 in the reader’s time zone. While it runs, Dripline watches the soil: if more than 3 in every 100 emails bounce, or anyone marks one as spam, that zone shuts off and you get a text.
