The First Email · free tool, no sign-up
The welcome email is the only one they actually asked for. Most brands spend it on a coupon.
It is the highest-intent moment in the whole program — somebody just typed their address in on purpose — and the usual answer is a banner, a product grid and 20% off. This writes the other kind: plain, from a person, one question, one link. It runs in your browser, hands you HTML you can paste into any platform, and never asks who you are.
- Plain HTML
- Any email platform
- Nothing sent anywhere
Before you read another tool page
Nobody can sell you the Primary tab.
Plenty will. The offer is usually a snippet of code and a promise of “50–100% more opens” — a number with no denominator, no window and no control group, which is the exact shape of claim this site exists to refuse. Here is the honest version, and it is the more useful one.
What you control
The parts that are actually yours.
- Authentication. SPF, DKIM and DMARC on the domain you send from. Table stakes, and the one item here a developer can finish this afternoon.
- Complaint rate. Google and Yahoo ask bulk senders to stay under 0.3%, and to sit well below it. This is the number that quietly decides everything else.
- Who you send to. Mailing people who have opened nothing in a year is the fastest way to teach a mailbox provider that your mail is ignorable.
- What the message looks like. A single-column plain message from a person does not look like a bulk campaign, because it is not built like one.
This tool touches the last one. It is the smallest of the four, and the only one a template can do anything about.
What nobody controls
The tab itself.
- Placement is per-recipient. The same email lands in Primary for one person and Promotions for another, on signals that include that reader’s own history with you.
- The model is not published. Anyone selling placement is selling a correlation they observed, not a mechanism they can operate.
- It moves. A trick that worked last quarter is a liability this one, and nobody sends you a notice when it stops working.
- Promotions is not a failure. For an offer it is the correct tab. It is the wrong place for hello, which is the whole argument of this page.
Google publishes what it actually asks of senders. Ten minutes, free, and better than any tool page: Email sender guidelines.
What this page is standing on
- Check it here
- Everything the tool does happens in this browser tab. Open the network panel and watch — filling the fields sends nothing, and the HTML is built on your machine.
- Published by the provider
- The complaint threshold and the authentication requirements are Google’s and Yahoo’s own, linked above rather than paraphrased.
- Not established
- Whether a plain first email lands in Primary more often than a designed one. I have not run that test with a holdout, I have not seen one published that I would trust, and I am not going to assert it because it would sell better. The case for plain is that it reads like a person — not that it beats an algorithm.
How it reads in an inbox
Two invented designed welcomes for comparison. Which tab you land in is Gmail’s call, not the template’s. This shows what your row says to someone scanning their inbox.
Opened
to me
Checked against the method
These check the email against the rules below. They don’t predict placement.
Your email, ready to paste
In your platform, set the From name to a person at the brand and Reply-to to an inbox someone reads.
Paste the HTML into your platform’s custom-HTML or code editor, and the plain text into its text-only version if it has one.
Why the first email is different
Gmail sorts mail by what it is. Person-to-person mail goes to Primary, and offers, newsletters and announcements go to Promotions. A welcome email built like an ad gets sorted as an ad. That isn’t a penalty. Promotions is where people go to shop, and your offer emails belong there.
Spam is where mail dies, and a different set of things decides it: authentication, complaint rate, how people engage with your mail, and where your list came from. No template fixes those, which is why the checklist below matters as much as the copy.
The first email is the exception worth making. Someone just gave you their address. The most useful thing you can send back is a short note from a real person with one question. It’s person-to-person because it is, not because it’s dressed up that way. Don’t use it to smuggle in an offer. If people reply, you’ve started a conversation, and their answers tell you what to send next.
What it won’t do
It won’t guarantee a tab. Gmail also weighs your sending history and how people treat your mail. A domain with a poor reputation can land in spam whatever the email says. And it won’t lift revenue on its own: moving the offer to email #2 changes when people buy, so judge it on the whole flow over a few weeks, not on email #1.
The sending checklist
The other half. These are the parts mailbox providers publish.
- Authenticate the domain. Gmail requires SPF or DKIM from every sender. Above 5,000 messages a day to Gmail, it requires DMARC too, and the From domain has to align with SPF or DKIM. Your platform’s domain settings page shows pass or fail.
- One-click unsubscribe. Bulk marketing mail to Gmail needs the one-click unsubscribe headers (List-Unsubscribe and List-Unsubscribe-Post). Yahoo asks senders to honor unsubscribes within 2 days. US law (CAN-SPAM) sets the outer limit at 10 business days.
- Keep spam complaints under 0.3%. That’s Gmail’s published line, and Yahoo’s too. Register your domain in Google Postmaster Tools so you can see yours.
- A person, and a real reply-to. From name: a person at the brand. Reply-to: an inbox someone checks, never no-reply. Accurate header information is also a CAN-SPAM requirement.
- An honest subject line. Lowercase and plain is fine. A fake “re:” or “fwd:” isn’t: it misleads the reader, and CAN-SPAM requires subject lines to reflect the content.
- The footer the law asks for. A valid postal address and a clear way to opt out, in plain text.
- Answer the replies. Decide who answers and how fast, and let people who replied skip the generic next email.
- Mail the engaged first. Campaigns go to people who opened or clicked recently. Stop mailing people who haven’t engaged in months. No bought lists, no image-only emails, no link shorteners.

Before you paste it into your account
The questions a free tool always gets.
- What’s the catch
- There is no sign-up, so there is no list to add you to. The thing I actually want is further down the page and it is clearly marked, optional, and behind a double opt-in. If you take the HTML and never come back, the tool did its job.
- Isn’t this just a template
- It is a template with a method attached and twelve checks that hold you to it. The checks are the part worth having: they are the rules I would apply reading your welcome email over your shoulder, and they run as you type.
- Will it beat my designed welcome
- I don’t know, and neither does anyone selling you the opposite. Run both. Split the entering audience, send plain to half and your current welcome to the other, and read reply rate and second-order rate rather than opens — opens have not had a reliable denominator since Apple Mail Privacy Protection.
- Who wrote the rules
- I run owned-channel revenue for consumer brands — in-house at a $100M+ business, then across a portfolio of DTC brands. The whole method is written up in The Second Order, free, twenty-four chapters, no form. If you want the argument before the tool, start there.
Every number on this page is one you can check on this page. If you find one that is wrong, tell me and I will correct it here rather than quietly.
The full build · 7 days
The whole change, one day at a time.
The seven-day plan for making this change: a baseline in three test inboxes, the authentication check, the rewrite, moving the offer to email #2, reply handling, list hygiene, and the day-7 before-and-after read in your own numbers.
The 7-day build
Day 1 · Baseline
Set up three test inboxes you control. Make at least one an old Gmail account you actually use. Sign each one up to your list the way a customer would, and screenshot where your current welcome email lands: Primary, Promotions or Spam. From your platform’s flow report, write down the current email #1’s open rate, click rate and placed-order rate for the last 30 days. That’s your before.
Day 2 · Authentication
Check SPF, DKIM and DMARC on your sending domain. Your platform’s domain page shows pass or fail. Use a branded sending domain, not the platform’s shared one. Make sure the From domain aligns with DKIM, and publish DMARC (p=none is the minimum) if it’s missing. Confirm one-click unsubscribe headers are on, and register the domain in Google Postmaster Tools.
Day 3 · Rewrite email #1
Build it with the generator above: a person’s name in From, a reply-to someone reads, 80–120 words, one question, one link to something worth reading, no images, buttons or codes. Send it 5–15 minutes after signup. Only promise to read replies if someone will.
Day 4 · Move the offer to email #2
Email #2 goes 24–48 hours later with the welcome offer, in your normal template. It will probably land in Promotions, and that’s fine: it’s an offer, and that’s where people look for offers. Email #3 is the story or the proof: why the brand exists, what customers say.
Day 5 · Reply handling
Decide who answers replies, and aim for one business day. Tag everyone who replies and let them skip email #2’s generic pitch; answer them as a person instead. Keep the answers in one doc. It’s free research for product pages, ads and the next email.
Day 6 · The rest of your reputation
Send campaigns to engaged subscribers first (opened or clicked in the last 90 days) and the rest later, or not at all. Stop mailing people with no engagement in six months, or send them one re-permission email. Watch the spam rate in Postmaster Tools. Keep it well under 0.3%.
Day 7 · Read the result
Sign the test inboxes up again with fresh addresses and screenshot where the new email #1 lands. Compare it with day 1: open rate, click rate, replies and placed-order rate for the flow, over the same length of window. Revenue moves with a lag because the offer moved to email #2, so give the whole flow two to four weeks before you call it. Keep whichever version wins.
