Sending a newsletter

From empty template to sent mailing, plus scheduling, resending and statistics.

Before you start you need two things: a verified sender and a list of contacts.

The template first

Under Templates you fix your house style: colours for the background, headings, text, links and buttons, the typeface and its weights, the content width, rounded corners, shadows and the thickness of dividers. You also set your logo, a header image and the footer, with your company name and address.

The footer can carry social links. Paste a link to your Instagram, Spotify or website and the icon is recognised automatically.

One template can be marked as the default. Every new newsletter then starts with that styling. Get this right once and you never have to think about it per mailing.

Building the newsletter

A newsletter is made of sections that you stack and drag around. There are seven kinds:

Section What for
Text Ordinary paragraphs with a heading
Text and/or image Text with a photo beside, above or below it
Images A gallery in columns, optionally all cropped to the same height, with captions
Button A clear call to action with its own label and URL
Video Paste a YouTube or Vimeo link; the thumbnail is fetched automatically
Divider / spacer A line, or simply some air between two blocks
HTML Your own HTML, for when you know exactly what you are doing. Unsafe tags are stripped

To the left of the preview are three tabs: Content, Settings and Sending. Everything you fill in there is saved as you go, so there is no save button. The right of the tab bar says whether it is saved, and shows you while it is saving.

Content holds the sections plus two fields:

Settings holds:

A preview on the right updates as you type. The two buttons above it show it at the width of a desktop screen or of a phone. Do check the phone view: that is where most people will read your newsletter.

Personalising

In your text you can use {voornaam}, {achternaam} or {naam} for first name, last name and full name. They are filled in per recipient.

If you do not know everyone's name, use a fallback: {voornaam|reader} becomes "reader" when the first name is unknown. Without a fallback you get an ugly gap in your sentence, so always do this.

Test first

Send a test mail to yourself. Look at it on your phone, not just your laptop; that is where it will be read. Check the subject line, the preheader, and whether your buttons are big enough to hit with a thumb.

Test mails count towards your monthly allowance.

Send settings

The Sending tab, to the left of the preview, holds where the newsletter goes:

The tags are meant for your own analytics tool, on your website for instance. Every link in the mail gets utm_source, utm_medium and utm_campaign added, so visits from your newsletter show up there as such instead of as "direct". The unsubscribe link, the "view online" link, mail and phone links and links to a spot inside the mail itself are left alone, and a link you already tagged yourself keeps your value.

The campaign name is the name of your newsletter by default. You can override it here, for instance to see several mailings under one heading. Once you send, the name is fixed: rename the newsletter later and the links in the mail that went out stay the same, so your numbers keep adding up. For different defaults across every newsletter on this page, set them under Campaign tagging on the newsletter overview.

Sending

Press Send and you first get a summary: which list it goes to, how many subscribers that is, which sender it comes from and how many emails you have left this month. If your allowance is too low, the app says so up front, with the number of recipients.

If the list or the sender is not set yet, the screen says which of the two, and you can only send once you fill it in under Sending.

After sending, the newsletter is locked. To send an amended version, duplicate it; you get a new draft with the same content.

New addresses go out in waves

For some addresses we know that mail arrives: a newsletter of yours was delivered there in the past year, or the person signed up themselves and clicked the confirmation link. For other addresses we do not know, for example when you just imported an old list. Such a list often holds addresses that no longer exist, and too much mail coming back hurts the delivery of all your mail.

If your send has at least 100 of those addresses, the newsletter goes out in waves. You see this beforehand in the summary.

  1. The newsletter goes straight to every address we know to work, plus a small, random group of the new addresses.
  2. After a few minutes we check how many of those came back or were reported as spam.
  3. If that goes well, a group twice as large follows, and so on until everybody has it. This is usually done within the hour.

The waves only go to whoever was on the list when you sent. If someone signs up while they run, you send it to them yourself afterwards with To the remaining contacts, as after any other send.

If 5 percent or more of the waves comes back because the address does not exist, or 1 percent or more reports the mail as spam, the send stops. You get a mail about it and see a notice with the newsletter. We look into it and let you know whether the rest still goes out. You cannot send the rest yourself at that point.

Addresses that did not exist leave your list by themselves. Your next newsletter starts with a small wave again, so a bad list gets cleaner step by step.

Scheduling

Switch on Send later and pick a moment. That moment is in your own timezone, shown under the field; see Account and signing in. The newsletter gets the Scheduled status and cannot be edited until then. To change something anyway, cancel the schedule; the newsletter returns to draft and is not sent.

Resending

A sent newsletter has two extra options. Both reach only the group in question, so nobody gets it twice:

Viewing online and sharing

Every newsletter carries a "view online" link, which works per recipient and keeps the unsubscribe link.

To share your newsletter on social media, create a share link. That is a public URL without an unsubscribe link and without a recipient. Newsletters without a share link cannot be reached that way at all, so sharing stays a deliberate choice. You can always revoke the link.

Statistics

After sending you see, per newsletter: recipients, sent, delivered, bounces, complaints, pending, opened and clicked. "Pending" is mail the receiving server has not said anything about yet. After a temporary refusal delivery is retried for up to a day, after which it lands under delivered or bounces after all. Below that are the most-clicked links, shown without the campaign tags so you can see at a glance which page each one is. A click on the unsubscribe link does not count as a click. The "view online" link works per recipient, but appears in that list as a single line, "View online", with all its clicks added together. Older newsletters may still show an "Unsubscribe link" line.

Click one of those numbers and you see who is behind it: the addresses that bounced, the complaints, the mail that arrived, and with tracking switched on also who opened or clicked. Useful when you want to know which addresses to clean up. Click a column heading to sort on that column, click again to reverse the order. Empty cells, such as people who have not opened yet, always stay at the bottom.

The per-recipient data is kept for 180 days. After that only the totals per newsletter remain and the list of addresses is empty. That is deliberate: we do not keep it longer than needed.

The dashboard shows your average open and click rate across all your sends.

A few things to keep in mind:

Delete a sent newsletter and its statistics go with it. Those cannot be recovered.
