Below are the top 10 most frequently asked questions regarding email marketing over the past 3 months. Complete with consice answers to help you understand and optimize your marketing campaigns.
Q1: What is a good open rate for email marketing?
This is the question everyone asks after hitting send, and the honest answer is, it depends. Open rates vary by industry, list quality, send frequency, and even time of year. Rather than chasing a universal number, the goal is to understand what's normal for your audience and improve from there.
That said, here are a few benchmarks.
The average industry open rate is visible in the Trends section of your email reporting, so you can see how you stack up against businesses like yours.
Proxy opens aren't counted. Apple's Mail Privacy Protection and other privacy tools trigger artificial "opens" that can distort your data. Constant Contact separates confirmed opens (likely human) from proxy opens (likely bots or automated tools) and only uses confirmed opens when calculating your open rate. This means your reported rate is more reliable than what some platforms show.
What actually moves the number:
A subject line that earns attention (not just clicks)
Sending to a permission-based list
Segmenting so the right message goes to the right people
Sending at the time your contacts are most likely to check their inbox
If your open rate is low, start with your subject line and list hygiene.
Q2: How do I build an email list?
Building an email list can feel intimidating, but the most important rule is simple: only add people who have given you permission to email them. A smaller list of engaged subscribers will always outperform a large list of people who didn't ask to hear from you.
Here's how to get started:
On your website or blog: Constant Contact offers several built-in sign-up form types — inline forms you can embed on any page, banner forms that appear at the top or bottom of your site, flyout forms, and pop-up forms. Each lets contacts choose what content they want, which means better engagement from day one.
On social media: You can share a Sign-up Landing Page directly on Facebook, Instagram, and other platforms. You can also run Facebook and Instagram Lead Ads that target people based on the characteristics of your current contacts. A powerful way to find people who are likely to be genuinely interested.
In person: The Text to Join feature lets customers text a keyword to subscribe — great for retail, events, or trade shows.
Q3: How do I keep my emails out of the spam folder?
Landing in spam is every marketer's nightmare. The good news: most spam triggers are preventable if you know what to look for. Spam filters are making decisions based on your content, your sending behavior, and your reputation as a sender, so all three need to be solid.
Watch your words. In both your subject line and email body, certain words and phrases are red flags for spam filters: "free," "guarantee," "earn," "act now," "click here," "call now," and similar language. Writing in ALL CAPS, using excessive punctuation (!!!), or overloading on symbols like $$ and % can also trigger filters. One instance might not sink you, but the more of these that appear throughout your email, the higher the risk.
Avoid image-only emails. Emails built as a single image, or that use too many images with very little text, are a common spam trigger. Balance images with real, readable text throughout the email. This includes multi-page pdfs sent to subscribers.
Protect your sender reputation. Content alone isn't the issue. If your emails consistently generate low opens, high bounces, or spam complaints, spam filters take notice and start routing your emails accordingly. Keep your list clean by removing unengaged contacts regularly, and only send to people who actually opted in.
Run a spam check before you send
Q4: What is a good click-through rate (CTR) for email?
If the open rate tells you whether people noticed your email, the click rate tells you whether they cared enough to act. It's more meaningful because it reflects actual engagement, not just inbox behavior.
A note on bot clicks. Security programs sometimes auto-click links in emails to scan for threats, which inflates your click count. If you have bot click filtering enabled in your account, Constant Contact shows you the number of likely bot clicks that were removed, so your data stays clean.
What drives higher click rates:
A single, clear call-to-action
Buttons over plain text links — they stand out visually
Making sure the link goes somewhere relevant and fast-loading
Segmenting so the content is actually useful to the people receiving it
Q5: How often should I send emails?
There's no universally right answer, but there is a signal you should always be watching: your engagement metrics. When your open rates start dropping and unsubscribes start increasing, that's your audience telling you they're getting too much.
For most small businesses, somewhere between 2–4 emails per month is a reasonable starting point. Enough to stay top of mind without overwhelming people. Weekly sends can work well, but only if your content is consistently valuable and your list is actively engaged with you. Dropping from weekly to monthly because you ran out of ideas is worse than starting at a sustainable pace and sticking to it.
What actually matters more than frequency:
Relevance — an email your contacts actually want to read will be tolerated at higher frequency than one that feels generic
Consistency — showing up on a predictable schedule builds expectations and trust
Segmentation — if you're sending to everyone on every campaign, you're almost certainly sending some people too much. Segmenting means high-engagement subscribers can get more, while occasional-buyer types get less
The best way to find your frequency sweet spot is to watch what happens after you change it. If opens go up and unsubscribes go down, you're on the right track. If the reverse happens, dial it back.
Q6: How do I write a subject line that gets emails opened?
Your subject line does more work than any other part of your email. If it doesn't earn the open, none of the rest matters. The good news is that there are concrete practices that consistently improve performance.
Keep it short and specific. Most inboxes display around 40–60 characters before cutting off. Front-load the most important information so it doesn't get truncated.
Add personalization. Including your contact's first name, or other details like their location or a past purchase,makes an email feel like it was written for them, not blasted to a list. Constant Contact supports subject line personalization using contact fields.
Use a preheader. Most email clients show a line of preview text after the subject line. This is extra real estate you should be using intentionally; a well-crafted preheader adds context and can meaningfully lift open rates.
Use emoji strategically. An emoji can add visual pop in a crowded inbox and signal tone. The key word is "occasionally" overuse makes you look unprofessional.
A/B test. Instead of guessing what works, test it. Constant Contact lets you run subject line A/B tests — sending two variations to a portion of your list and automatically sending the winner to the rest.
Q7: What is email deliverability, and how do I improve it?
Deliverability is the measure of whether your emails actually reach your contacts' inboxes, as opposed to being bounced, filtered to spam, or blocked entirely.
Internet Service Providers (ISPs) and inbox providers like Gmail, Yahoo, and Outlook use sophisticated filters to decide what gets through. Those filters look at a combination of factors:
Your sender reputation. This is built over time based on how your contacts engage with your emails. High open rates, low bounce rates, and few spam complaints signal that people want your mail. Consistently poor engagement, or worse, spam complaints chips away at your reputation and makes future emails harder to deliver.
Your content. Certain words, excessive images, all-caps text, and suspicious links all raise red flags.
Your list quality. Sending to a lot of bad addresses drives up your bounce rate, which damages your reputation. Regularly cleaning your list — removing hard bounces and disengaged contacts — keeps your deliverability healthy.
What you can do today:
Only email people who explicitly opted in
Never purchase lists
Keep your list clean by removing hard bounces promptly
Constant Contact also maintains sending infrastructure and relationships with ISPs to help your emails reach inboxes, one of the core things a reputable email service provider does for you.
Q8: Does email marketing still work? What kind of ROI can I expect?
The short answer: yes, email marketing absolutely still works, and it's still one of the highest-ROI marketing channels available to small businesses. The longer answer is that how you do it matters more than whether you do it.
Generic, infrequent, or irrelevant emails won't move the needle. But a well-timed, well-segmented email to an engaged list can drive real revenue. Constant Contact lets you track revenue directly generated from your email campaigns, SMS messages, and automations, so you can see exactly what your email program is contributing, not just guess.
Reporting in your account also shows your Conversion Rate — the percentage of email opens that resulted in actual orders — alongside total orders generated, so you can tie campaign performance to business outcomes.nes that don't:
A clean, permission-based list
Segmentation and personalization
Automation to send the right message at the right moment without manual effort every time
Consistent sending — not a blast once a quarter when you need sales
Q9: How do I grow my email list fast?
"Fast" list growth and "quality" list growth aren't the same thing, but you can absolutely grow quickly without sacrificing either, if you use the right tools and tactics together.
Use multiple capture points simultaneously. Don't rely on a single sign-up form buried in your website footer. Constant Contact gives you a full toolkit: inline forms, banner forms, flyout forms, and pop-up forms — each targeting visitors at different moments
Activate social and paid channels. Create a Sign-up Landing Page and share it across your social profiles. Better yet, run Facebook and Instagram Lead Ads — they let you target people who match the profile of your existing subscribers and present them with a sign-up form. This is the fastest way to reach new audiences who haven't found you yet.
Enable Text to Join. Give in-person customers a frictionless way to subscribe. You share a short keyword and a number; they text it and they're on your list. It takes a few minutes to set up and works anywhere.
Give people a reason to sign up. A form alone isn't enough. An incentive, a discount, a free resource, early access to something dramatically increases the conversion rate of any sign-up form. Make it clear what subscribers are getting and how often you'll email them.
Q10: How do I use AI in email marketing?
AI has moved to built-in features in most email marketing tools, and Constant Contact is no exception. If you're curious about where AI can actually save you time and improve results — here's what's available today.
Content Generator. Constant Contact's AI writing tool. You give it a short description or a few keywords, and it generates complete email content — copy, structure, and in some cases, imagery, that you can then edit and make your own. It also works inside the email editor itself if you get stuck mid-draft, and it supports landing pages, social posts, and SMS messages.
Note: The Content Generator is not available on all plans. If you don't see it in your account, you may need to upgrade.
AI in automations. When building welcome series or nurture sequences in the Automation Path Builder, you can use the AI Content Generator directly while editing each email step — helpful for getting a solid draft out quickly even when you're managing a multi-step sequence.
AI-generated template selection. When picking a template, you can describe what you want to create and the system will surface template options that match — skipping the scroll-through-everything approach.
The best use of AI in email marketing right now isn't to replace your voice, it's to remove the blank-page problem. Let the generator draft, then edit it to sound like you. That's faster than starting from scratch, and better than sending something generic.
