When evaluating any platform, the features that matter most are automation capabilities, list segmentation, native integrations with your existing software (e.g. CRM, e-commerce, booking page), and analytics reporting for key metrics such as click-through rates (CTR), bounce rates, and open rates.

A CRM, otherwise known as a customer relationship management system, stores customer data and maintains a record of past interactions across various touchpoints. When a CRM is connected to an email marketing platform, the two systems share data in real time, enabling precise targeting.

The practical benefit is segmentation accuracy. A CRM can surface customers who haven’t bought in a set period of time, purchased a particular product, or spent above a pre-defined threshold. Email campaigns built on data perform better than campaigns built on over-the-top broadcast emails. Re-engagement sequences, win-back offers, and cross-sell campaigns all improve when they pull from structured customer data.

Most modern email marketing platforms have built-in CRM functionality, but many companies already have existing systems, which makes real-time data syncing features all the more important.

At Marketable Branding, we use Mailerlite as our primary email marketing tool, but we use Flodesk for our CRM, as they have a very generous plan for storing inactive recipients. If you want a minimalist, easy-to-use CRM, Flodesk is worth looking into.

The starting point is list building. Collect email addresses through opt-in forms, purchases, lead magnets, in-person sign-ups, and social media.

Once a list exists, build a welcome sequence – three to five emails sent upon sign-up introduces your business, sets communication expectations, and delivers promised content. This is the highest-leverage automation a small business can build and the one that produces the highest ROI. Statistics show welcome flows are one of the best times to make a sale, because the prospect is already actively engaging with your brand. Sending four to eight emails per month tends to produce the highest ROI. Most small businesses under-send rather than over-send, fearing they’ll annoy their audience, however, 77% of people prefer receiving promotional messages through email when compared to direct mail, social media, or SMS.

Measure performance at the campaign level; open rates, click-through rates, conversion rates, and unsubscribe rates. Review after each send and use the data to inform any future campaigns. Over time, patterns emerge: which subject lines perform, which days drive engagement, which content types generate clicks, etc etc.

The goal is regularity, not frequency for its own sake.

A good email marketing strategy draws on several message types. Newsletters build ongoing relationships and establish trust, promotional emails drive purchases around specific offers, launches, and seasonal events.

Transactional emails (e.g. order confirmations and shipping updates) create opportunities for low-pressure upsells.

The most effective campaigns segment message types by audience. Segmented email campaigns drive 30% more opens and 50% more click-throughs than unsegmented campaigns. A long-tenured customer receives different messaging than a brand new subscriber. Someone who clicked a specific product receives follow-ups relevant to said product. This won’t apply to every business, but for those that sell many products, it’s worth prioritizing. The investment in segmentation logic pays a measurable return at every send.

Open rates are largely influenced by subject lines. Subject lines that perform consistently tend to be specific, curiosity-driven, and tied to a clear value proposition.

Click-through rates respond to content clarity and clear call-to-actions. A clear CTA with a button, clean whitespace, and copy that explains what the reader should do will consistently outperform buried text links.

Sender reputation is one of the most important aspects of a long-term email marketing strategy. Your sender reputation is what primarily determines whether your email will end up in the spam box or the primary one. Sending attachments that are over 100KB is a common deterrent for making it into the inbox. Ensuring you're compressing your images and separating sections is crucial to email sender reputation.

Overcleaning email lists is another common trap businesses have fallen into. With the rise of spam filters, many marketers have suggested frequent email list cleans, and or, removing people from your email lists. Although well-intentioned, this advice can be rather harmful.

In order to understand why, it might help to understand it from the recipients shoes:

If you received an email from your favorite soap brand, one you’ve bought from on a regular basis for many years, are you likely to unsubscribe to their email list because you decided not to buy during their Easter sale? Probably not.

Generally, we recommend cleaning your mailing list once every two years – one at the very earliest. This might sound extreme when compared to common advice, but this simply is common practice. Many things can affect open rates, and as previously discussed, open rates are not the best metric to track in 2026.

Before deleting another inactive contact from your list, be sure to check your email size, bounce rates, and configuration settings (the more common reasons your emails aren’t delivering).

Another common mistake is overcleaning your email list. Nowadays, business owners are flooded with misguided advice everywhere they turn.

IMPORTANT: List scrubbing is different from list cleaning. List scrubbing is the practice of verifying your email list. It’s not that rare to find that someone opted into your freebie with an old email address, or that they accidentally typed a 2 instead of a 1 at the end of their email.

There are many platforms that offer this as a service, and some modern email providers even include this as a built-in feature. The one we use (and recommend) is Lumrid.

Email marketing remains one of the best digital channels for customer retention. The combination of owning your audience and scalable automation makes well-executed email strategies compound.

If you're a small business that hasn't invested in email marketing, the data makes the case all the more compelling.
