My friend Tom runs a small landscaping business, and a couple of years ago he signed up for an email tool because a Facebook ad promised it would triple his bookings. Six months later he was still using the free trial features because he never got around to setting up automation, and he was paying $40 a month for a tool that was basically sending one newsletter here and there. That's the story I think about every time someone asks me how to pick email marketing software.
Most guides on this topic just list every feature a platform has and call it a day. I want to do something more useful, which is walk you through the exact things I personally check before recommending or paying for any email tool, based on what actually matters once you're using it day to day instead of just browsing a pricing page.
Why the Wrong Email Tool Costs You More Than Money
Picking the wrong platform doesn't just waste your monthly subscription fee. It costs you time relearning a new system if you switch later, it costs you deliverability if the platform has a poor sending reputation, and it costs you opportunities if the automation features are too limited to actually nurture leads while you sleep.
The tricky part is that most of these costs are invisible until you're already a few months in. A platform can look perfectly fine during a free trial and still fall apart once your list grows past a certain size or you try to build a more complex campaign. That's why I check specific things upfront rather than just going with whatever looks nicest in a demo.
The 7 Things I Check Before Paying for Any Email Tool
1. Deliverability Track Record
This is the one people skip most often, and it's arguably the most important. It doesn't matter how beautiful your emails look if they're landing in spam instead of the inbox.
According to testing by EmailToolTester across 15 major email service providers, the average deliverability rate came out to 83.1 percent, meaning roughly 16.9 percent of emails never reach the intended inbox. That gap between platforms is significant, so before I commit to any tool, I look for independent deliverability testing rather than trusting the platform's own marketing claims.
2. Pricing Structure, Not Just the Sticker Price
I always look past the advertised starting price and figure out how the platform actually charges. Some bill by contact count, some by emails sent, and some lock key features behind higher tiers. A $10 a month plan can turn into $80 a month fast if you're not paying attention to how pricing scales with your list.
I also check whether the platform charges for unsubscribed or inactive contacts sitting in your account, since that's a sneaky cost that catches a lot of small businesses off guard.
3. Ease of Use for Non Technical Teams
If setting up a simple automated welcome sequence takes an hour of clicking through confusing menus, that's a real problem for a small business without a dedicated marketing person. I test this by trying to build a basic three email automation sequence during the free trial and timing how long it takes me.
A tool that respects your time here will usually respect it in other areas too, like reporting and campaign building.
4. Automation Depth
Basic automation like welcome emails and abandoned cart reminders is table stakes at this point, so I look past that to see what happens when you need something slightly more complex. Can you branch a sequence based on whether someone clicked a link? Can you trigger an email based on a tag being applied by another tool in your stack?
Not every small business needs advanced automation right away, but I always check whether the platform can grow with you before I recommend committing long term.
5. List Segmentation Options
Segmentation is what turns a generic newsletter into something that actually converts. I check whether a platform lets you segment by purchase history, engagement level, and custom tags, since those three alone cover most small business use cases.
Some cheaper platforms limit segmentation to their higher priced tiers, which defeats the purpose of choosing an affordable option in the first place if you end up needing to upgrade just to use basic targeting.
6. Integration With Your Other Tools
Your email platform needs to talk to whatever else runs your business, whether that's Shopify, WordPress, a CRM, or a simple form builder on your website. I check the integration list before signing up for anything, because building a custom connection later using Zapier or a similar tool adds cost and complexity you probably don't want.
If a platform doesn't integrate directly with your ecommerce or website tool, that's often a dealbreaker on its own regardless of how good the rest of the features look.
7. Customer Support Quality
I look at recent reviews specifically mentioning support response times, not just star ratings, since ratings can be misleadingly high even when support is genuinely slow. A platform that only offers email support on lower tiers can leave you stuck for a day or two if something breaks during a launch.
I also check whether there's a real knowledge base or community forum, since that self-serve option often gets you an answer faster than waiting on a support ticket anyway.
Red Flags I Watch Out For
A few things make me walk away from a platform immediately. Vague pricing pages that hide the real cost until checkout are one, since transparency usually correlates with how the company treats customers overall. Another is a free trial that requires a credit card upfront with no clear cancellation process, which tells me the company is banking on people forgetting to cancel.
I'm also wary of platforms with almost no independent reviews outside their own website, since that usually means either the product is brand new or reviewers haven't had a great experience worth sharing publicly.

Frequently Asked Questions
What is the most important feature in email marketing software?
Deliverability matters most, since even the best designed email is useless if it never reaches the inbox.
How long should I test an email marketing tool before committing?
Two to four weeks is usually enough to test setup, automation, and a real campaign send.
Do small businesses need advanced automation features?
Not immediately, but choosing a platform that can grow into advanced automation saves you a painful migration later.
Should I prioritize price or features when choosing email software?
Prioritize features that match your actual use case first, then compare pricing across tools that already meet your needs.
Is it worth paying more for better customer support?
Yes, especially if you don't have technical staff who can troubleshoot issues on their own.
How do I check a platform's real deliverability rate before signing up?
Look for independent deliverability testing sites rather than relying only on the platform's own claims.
