The truth is, there’s no magic wand for perfect deliverability. Instead, you should focus on using the right strategies consistently.
Some fixes are quick and straightforward, while others take time and effort, but every step counts. We break down those strategies into manageable pieces so you can pick what works for your goals and resources.
Let’s unpack how to get your emails where they need to go, starting with the basics and working up to long-term wins.
Grouping strategies: Effort, time, and cost
Improving email deliverability doesn’t have to feel overwhelming. To keep things practical, it helps to break strategies into three groups: quick fixes, mid-term improvements, and long-term plans. Each group has its own level of effort and payoff, so you can pick what works best for your needs and resources.
Quick fixes: Easy wins for fast results
These are the low-hanging fruit of email deliverability. They’re simple to address, require little time, and can make an immediate difference.
| Strategy | Time | Effort | Cost |
| Clean your email list | Low | Low | Low |
| Avoid spam trigger words | Low | Low | None |
| Authenticate your emails | Low | Low | Low |
| Set a consistent sending schedule | Low | Low | None |
Mid-term improvements: Building a better foundation
These strategies take more time and effort, but they’re worth it. They help build stability and improve how your emails perform over time.
| Strategy | Time | Effort | Cost |
| Segment your audience | Medium | Medium | Medium |
| Warm up your sending domain | Medium | Medium | Low |
| Monitor your sender reputation | Medium | Medium | Low |
| Optimize your email design | Medium | Medium | Medium |
Long-term strategies: Playing the long game
If you’re serious about email deliverability, these are the heavy hitters. They take more effort and investment upfront but bring lasting benefits.
| Strategy | Time | Effort | Cost |
| Build an engaged email list | High | High | Medium |
| Conduct regular deliverability audits | High | High | High |
| Develop a re-engagement strategy | High | High | Medium |
| Invest in email compliance | High | High | High |
Breaking your efforts into these groups helps you tackle what’s manageable now while keeping an eye on the bigger picture. It’s about making steady progress and staying ahead of anything that could keep your emails out of the inbox.
With the strategies grouped, it’s time to tackle the details. Let’s start with quick fixes – simple steps you can take right away to get your emails on the right track.
Quick fixes: Strategies you can implement right now
These quick fixes are a great place to start if you’re looking for easy wins. They don’t take much time or effort but can make a real difference in how your emails land in inboxes instead of spam folders.
Clean your email list
Over time, some addresses on your list will become invalid due to typos, job changes, or abandoned accounts. Some might even be spam traps. Sending emails to these bad addresses increases your bounce rate, which can hurt your sender reputation.
A tool like Bouncer can help identify which addresses are no longer valid. It only takes minutes, but the results? Remarkable. Once you’ve cleaned up your list, your emails will likely reach active and engaged recipients.

Avoid spam trigger words
Words like “Free,” “Act Now,” or “Limited Time” can make your emails look spammy to filters, even if your content is legitimate. These filters scan subject lines and body text for phrases commonly used in junk mail. Here are some more phrases to avoid:
| Earn $ | Make $ | Apply now |
| Free gift | Prices | Reverses |
| Lifetime | Sample | Special promotion |
| Opportunity | Urgent | Fast cash |
| Stop | Web traffic | No investment |
| Great offer | Double your income | Hidden |
| Hidden assets | Increase sales | 100% free |
| Obligation | Act now | Affordable |
| Free info | No hidden costs | Free installation |
| Save $ | Solution | Earn extra cash |
Instead, use natural language and focus on being direct about what your email is about. For example, instead of saying “Limited Time Offer!” you could say “Exclusive Discount for Our Subscribers.” Test different phrases to see what resonates while avoiding the spam folder.

Authenticate your emails
Email authentication might sound technical, but it’s easier than you think. It’s like putting a signature on your messages to prove they’re coming from you. Setting up SPF, DKIM, and DMARC records tells email providers that your messages are genuine and not from spammers pretending to be you.
Most email marketing platforms have guides to help you set up SPF, DKIM, and DMARC. Once it’s done, your emails are more likely to land in the inbox instead of getting flagged.
- Time: Low
- Effort: Low
- Cost: Low
Set a consistent sending schedule
Sending emails randomly or with long gaps between campaigns can look suspicious to email service providers. It’s better to keep a steady rhythm, like sending newsletters every Tuesday morning or promotional emails once a week.
Consistency helps build trust and lets your audience know when to expect your messages. Start by picking a schedule that works for your team and stick to it. Over time, this simple habit can improve your email performance.

Mid-term improvements: Sustainable strategies
Once you’ve tackled the quick fixes, it’s time to dig into strategies that take a bit more effort but lead to steadier, long-lasting results. These mid-term improvements are about building a stronger foundation for your email campaigns.
Segment your audience
Not all subscribers are the same, so why treat them like they are? Splitting your audience into smaller groups based on interests, behavior, or demographics lets you send emails that speak directly to them.
For instance, you might send a thank-you email to loyal customers while creating a special discount campaign for first-time buyers. It takes some time to set up, but when people feel like your message is just for them, they’re more likely to open and click.
- Time: Medium
- Effort: Medium
- Cost: Medium
Warm up your sending domain
If you’re starting with a new IP address, don’t send a flood of emails immediately – it’s a red flag for spam filters. Instead, start small and gradually increase the number of emails you send over a few weeks.
Called email domain warm-up, this gradual build helps email providers see your domain as trustworthy. Treat it as introducing yourself to a new crowd – start with a few people, then expand as you build credibility.
- Time: Medium
- Effort: Medium
- Cost: Low
Monitor your sender reputation
Your sender reputation is like your credit score for email. A good reputation helps your emails land in inboxes, while a bad one sends them to spam.
Tools like Google Postmaster or Bouncer can help you keep track of email performance metrics like bounce rates and spam complaints. Regularly checking these numbers can alert you to problems before they get worse. If something looks off, you can adjust to keep your reputation strong.

- Effort: Medium

Optimize your email design
People read emails on all kinds of devices, from laptops to smartphones, so it’s important to make your emails easy to read no matter where they’re opened. Use clear fonts, a good balance of text and images, and buttons that are big enough to click on a small screen.
Test your emails on different devices before you hit send. A well-organized email is more engaging to read AND less likely to increase spam complaint rate.

Long-term strategies: Investing in deliverability excellence
When you’re ready to take your email game to the next level, long-term strategies are where the real growth happens. These steps take more time and effort, but they’re worth it if you want lasting results.
Build an engaged email list
Focus on growing your list with people who genuinely want to hear from you. Skip the shortcuts – purchased or scraped lists aren’t worth the headaches they cause.
Instead, use opt-in forms on your site or during checkout to gather contacts who are truly interested. Over time, an engaged list means fewer spam complaints and better results for every email you send.
- Time: High
- Effort: High
- Cost: Medium
Conduct regular deliverability audits
Problems with your emails can sneak up on you, which is why it’s smart to do regular checkups. Algorithms and spam traps keep evolving. Thankfully, tools like Bouncer make it easy to spot things like high bounce rates or spam flags before they hurt your reputation.
Think of it as maintenance for your email campaigns. When you catch small issues early, you can keep things running smoothly and avoid more significant problems down the road.
Pro tip: Bouncer’s Deliverability Kit is packed with tools to help you stay ahead of email problems. You can check how many emails actually land in inboxes, test your SPF, DKIM, and DMARC setup, and keep an eye on blocklists for your domain and IP.
It’s easy to set up and gives you precise results, so you know what’s working and what needs fixing. If you want your emails to reach the right people, this kit has everything you need.

Develop a re-engagement strategy
Subscribers lose interest – it’s a reality of email marketing. People change jobs, switch email addresses, or simply stop engaging. While holding on to every contact is tempting, keeping inactive subscribers on your list can hurt your domain reputation and email metrics.
What matters is how you respond when engagement starts to fade.
Start with a win-back campaign. Send a targeted email series to subscribers who haven’t opened your messages in a while. These email messages can include a friendly check-in, a special discount, or a simple “We miss you” message with a clear call to action. The goal is to spark interest and see who’s still paying attention.
If they don’t engage after your campaign, it’s time to clean house. Remove inactive email addresses from your list. While it might feel counterintuitive to delete contacts, keeping your subscriber list focused on active, engaged users improves your deliverability rates and spam complaint rate.
A strong re-engagement strategy takes time and effort, but it’s worth it. By focusing on the people who want to hear from you, your email content will land in more inboxes, and your campaigns will perform better overall.

Invest in email compliance
Laws like GDPR and CAN-SPAM might sound complicated, but they’re about playing fair.
What do they entail? It’s about creating transparent practices, managing explicit consent, and building trust with your audience. Here’s how to do it in three quick steps:
- Collect explicit consent
Use clear, double opt-ins when adding subscribers to your list. This ensures that every email address belongs to someone who actively wants your marketing emails. - Add the essentials to every email
Always include a visible unsubscribe link, your physical address, and clear sender information. These are non-negotiables under most email regulations. - Audit your practices regularly
Check your email processes for compliance gaps. Tools like Bouncer can help verify that your sending domain is properly authenticated (SPF, DKIM, DMARC) and compliant.
Compliance may require upfront effort and costs, but it protects your sender’s reputation and increases the chances of your emails landing where they should.

How to improve email deliverability in 2025?
Email deliverability refers to getting your emails into subscribers’ inboxes rather than being flagged by a spam filter. For 2025, focus on email practices that protect your domain reputation, such as authenticating your email domain and avoiding spam traps.
Monitor performance metrics like deliverability rates and spam complaint rate to identify areas for improvement. Regularly clean your subscriber list to remove invalid addresses and unengaged subscribers.
Following regulations like the CAN-SPAM Act and the Canadian Anti-Spam Legislation helps keep your campaigns compliant and builds trust with email providers.
Does DKIM improve deliverability?
Yes, Domain Keys Identified Mail (DKIM) can help improve deliverability rates. DKIM adds a digital signature to your emails, verifying that they come from your own domain. This extra layer of authentication helps email providers trust your sending server and improves inbox placement.
When paired with Sender Policy Framework (SPF) and DMARC, DKIM strengthens your email marketing strategy and protects your domain name server from misuse.
