  • Email Deliverability Checklist

    Inbox placement · a practical checklist

    Before the first send: a deliverability checklist.

    Inbox placement is earned over time. A clean domain, expected messages, and a list built with permission give a new sender a steadier start. Use this checklist before your first campaign and revisit it when the sending setup changes.

    First principle: no checklist can promise an inbox placement rate. Receiving providers make their own decisions based on authentication, recipient signals, message patterns, and other factors. Treat the items below as sound setup and list-care habits, then monitor how your own audience responds.

    1 · Authenticate the domain you send from

    Set up SPF with every legitimate sender in mind.

    SPF tells receiving systems which services may send mail for a domain. If your domain sends through several services, coordinate the records carefully with your domain host and providers. Follow each provider’s current instructions rather than pasting records from an old setup.

    Enable DKIM signing.

    DKIM adds a signature that receiving services can check. Publish the exact DNS records supplied by your email platform and confirm they show as verified inside the account.

    Publish a DMARC policy and review alignment.

    DMARC lets domain owners tell receiving systems how to handle messages that fail SPF and DKIM checks. Start with the guidance that matches your sending setup; consult a domain administrator before tightening policy if you also use forwarding, support, or transactional services.

    Google’s Email sender guidelines ↗ and Yahoo’s Sender Best Practices ↗ describe current requirements and recommendations for mail to their users. Requirements can differ by sending volume, so check the current provider pages when your audience grows.

    2 · Keep the list rooted in permission

    Know where each address came from.

    Keep a record of the signup form, event, purchase, or other context that explains why someone expects your email. Do not import a purchased or scraped list into a newsletter tool.

    Use a signup promise you can keep.

    Say what kind of messages you will send and how often. A reader who expects a monthly guide may not welcome daily promotions.

    Make unsubscribing simple.

    Include a visible unsubscribe option and honor it promptly. Keep your suppression list so an opted-out address is not accidentally added again.

    3 · Protect list quality

    Remove hard bounces and known invalid addresses.

    Use the email platform’s suppression tools and investigate repeated delivery errors rather than resending to the same broken addresses.

    Let inactive readers choose.

    If engagement fades, try a short re-engagement note or pause messages to people who no longer respond. Do not send more often just to force a signal.

    Start with a steady, expected cadence.

    For a new domain or a list that has been quiet, begin with your most engaged subscribers and send at a pace you can maintain. Avoid sudden, unexplained volume spikes.

    4 · Review the message like a subscriber

    Use a recognizable sender name and a real reply path.

    Let readers identify who is writing, and have a monitored way to receive replies.

    Check links, images, and the phone preview.

    Send a test to common inboxes. Confirm that the main action is clear, images have helpful alt text, and the message still makes sense with images turned off.

    Match the subject line to the content.

    Make a clear promise without misleading urgency or language that could surprise the reader.

    5 · Monitor signals after sending

    Review accepted, bounced, and complained-about messages, along with unsubscribes and meaningful clicks or replies. Compare trends over several sends rather than treating one small campaign as a universal verdict. Investigate a sudden change in one segment, signup source, or inbox provider before changing everything at once.

    If you use an email platform such as MailerLite, verify the sending domain inside its current account settings and follow the provider’s setup steps. Our MailerLite review covers the plan fit; this checklist applies regardless of which tool you choose.

    Pre-send pause: Can you name where these readers signed up? Does the sender domain authenticate? Does each person know why this email arrived? Can they leave easily? If any answer is unclear, fix that first.

  • First Welcome Sequence

    Email playbook · a six-minute field note

    Your first welcome sequence, without overbuilding it.

    A welcome sequence gives new subscribers a clear beginning. It can explain what they signed up for, offer something useful, and make the next step easy to find. Three thoughtful emails are usually enough to start.

    Right away

    01 · Confirm the promise

    Welcome them, deliver the thing they asked for, and say what will arrive next.

    Two or three days later

    02 · Give one useful idea

    Share a short tip, a starter checklist, or an answer to a common question.

    A few days after that

    03 · Invite a natural next step

    Point to a product, service, event, or reply—without turning the sequence into a hard sell.

    Email 1: make the first moment easy

    Send the first message promptly after signup. Use the subject line to match the signup context rather than a vague “Welcome!” If a reader requested a guide or discount, put the delivery link near the top.

    Subject: Here’s the checklist you asked for
    Opening: Thanks for signing up. You can download the checklist here. I’ll send a short note later this week with one way to use it.

    Keep the promise specific. If this is a weekly letter, say which day it arrives and what kinds of notes subscribers can expect. Add a visible unsubscribe link and use your usual sender name so the next message feels familiar.

    Email 2: help before you pitch

    Wait long enough that the first email has had a chance to be read. Then answer a question your audience often asks. One small example is better than a long catalog of everything you know.

    Subject: One quick way to use the checklist
    Opening: Start with the first question: who is this for? A useful signup page names the reader, the result, and what happens next.

    This email can also invite a reply. Ask a genuine, answerable question such as “What are you trying to make easier this month?” Replies can reveal useful content ideas and help make the relationship feel human.

    Email 3: show the next step

    Connect the reader’s goal to one relevant next action. That might be a product page, a consultation, an event registration, or another guide. Explain who it is for and who should skip it. A good invitation can be direct without making the whole sequence feel like a sales funnel.

    Subject: Ready for the next step?
    Opening: If you want help putting this into practice, here’s a short overview of the service. If you’re still exploring, keep the checklist and look out for Friday’s note.

    Set the automation up with care

    1. Choose one signup form and one clear trigger.
    2. Send only the content the subscriber expects from that source.
    3. Check timing, links, personalization fields, and unsubscribe behavior on a test address.
    4. Exclude people who already bought or completed the goal, when that is relevant and technically supported.
    5. Review replies, clicks, unsubscribes, and complaints across a meaningful number of sends.

    Keep it small at first. Write the three emails, test the links on a phone, and ask whether each message gives the reader a reason to stay. Add branches only when you can name the different subscriber need they serve.

    Build it in a tool that fits

    If your platform supports an automation builder, create one simple sequence and send a test through the whole path before publishing the form. MailerLite’s plans include a limited number of automations on Free and more on paid tiers; verify the current allowance on its pricing page. Read our MailerLite review for the current plan outline.

    A useful sequence feels like a helpful beginning—not a maze. Start with one audience, one promise, and a next step worth taking.
