Email Marketing Under 1,000 Subscribers: What You Actually Need

Below about a thousand subscribers, every email platform is functionally the same product: a form, an editor, a send button, and a list. The differences that matter at ten thousand subscribers, like segmentation, automation branches, and deliverability tooling, do not matter yet because you do not have enough data to use them.

So the decision should take twenty minutes, not a week of comparison shopping. Here is what actually affects your results at this size.

The one thing that determines whether your email arrives

Deliverability is about three things, and none of them is your platform choice.

Domain reputation. If you send from a fresh domain, you have no reputation, and the first hundred emails are the hardest you will ever send. Warm it: send to yourself and a handful of people who will open, for a week, before any real send.

Authentication. SPF, DKIM, and DMARC records. Every platform gives you the values to paste into DNS. If you skip this, a meaningful fraction of your mail goes to spam and you will blame the platform.

Engagement. Mail providers rank senders by whether people open and click. A small list that opens is worth more than a large list that does not. This is why buying a list is not just unethical but self-defeating: it destroys the signal that gets you into inboxes.

Note what is not on that list: which company sends your email.

The free tiers, compared honestly

The Mailchimp trap is the send cap. Five hundred contacts sounds fine until you want to send four times in a month, at which point you have used your allowance on a list you have not grown yet. ConvertKit's thousand is more generous for a weekly newsletter.

What to actually spend time on

The welcome email. The single highest-open email you will ever send is the one that arrives right after someone subscribes. Open rates on welcome emails routinely run three to five times a normal send. Write it properly: who you are, what they will get, how often, and one link to something useful.

The send rhythm. Weekly beats "whenever I have something". A predictable schedule is the difference between a subscriber who remembers you and one who marks you as spam after four months of silence and then a sudden email.

The subject line. This is where open rates are won and lost, and it is the only part of the email most people see. Short, specific, no cleverness. "Three things I got wrong about pricing" beats "My thoughts on pricing strategy this month".

Plain text. HTML templates with a header image and three columns look like marketing and get treated as marketing. A plain email that looks like a person wrote it gets replies, and replies are the strongest possible deliverability signal.

What not to spend time on

Templates. You will use one. Pick the plainest available and stop.

Segmentation. With 400 subscribers, segmenting by engagement creates segments of eleven people. Wait until you have enough volume for a segment to be statistically meaningful, which is roughly a thousand per segment.

Automation sequences. A five-email nurture sequence sent to a list of 200 will reach the fifth email with maybe thirty people. Write one good welcome email instead.

A/B testing. At small volumes the difference between two subject lines is indistinguishable from noise. Test ideas, not variants.

The migration question

People ask which platform to start on to avoid migrating later. The answer is that migrating email lists is one of the easier migrations in software: every platform exports a CSV of subscribers, and every platform imports one. What you lose is automation history and template design, both of which you should not have built yet.

So pick on price and interface, and plan to move at around two to three thousand subscribers, which is when the pricing curves diverge and the feature differences start to matter.

What I would do

Start on whichever free tier covers your list size with room for four sends a month. Set up SPF, DKIM, and DMARC before the first send, not after. Write one welcome email that is genuinely good. Send weekly, plain text, one idea per email.

That is the entire strategy at this size, and it will outperform a more sophisticated setup run inconsistently, which is the actual competitor you are up against.
