Boost Your Email Deliverability with Spryka ePostMailer: 5 Proven TipsEmail deliverability is the difference between your message reaching a subscriber’s inbox or getting lost in spam. Spryka ePostMailer offers robust sending tools, templates, and analytics — but even the best platform can’t guarantee inbox placement without the right practices. Below are five proven, actionable tips to improve deliverability when using Spryka ePostMailer, plus practical steps and examples you can implement today.
1. Maintain a Clean, Engaged List
Keeping your list clean is the foundation of deliverability. ISPs use engagement signals (opens, clicks, replies) to judge sender reputation. Low engagement and high bounce rates hurt that reputation.
- Remove hard bounces immediately. Spryka ePostMailer’s bounce reports make this simple — export and delete or suppress hard-bounced addresses.
- Suppress repeated soft bounces. Addresses that soft-bounce multiple times over weeks should be moved to a re-engagement or suppression segment.
- Segment by engagement. Create segments for “Active” (opened or clicked in last 90 days), “Lapsing” (90–180 days), and “Dormant” (180+ days). Send different content to each group; gradually suppress Dormant subscribers if they don’t respond.
- Use double opt-in for new subscribers. This reduces fake or mistyped emails and increases initial engagement.
- Run periodic list hygiene: remove role accounts (info@, admin@), disposable addresses, and addresses from data append lists that weren’t opt-in.
Practical Spryka steps:
- Use the platform’s list filters to create engagement segments.
- Schedule an automated workflow that deletes or moves hard bounces to a suppression list.
- Enable double opt-in in your signup forms and API settings.
2. Authenticate Your Sending Domain (SPF, DKIM, DMARC)
Authentication is technical but essential: it proves to ISPs that you’re an authorized sender and reduces the chance your mail is blocked or spoofed.
- SPF: Add a TXT record to your DNS authorizing Spryka’s sending IPs. Check Spryka’s documentation for the exact SPF value to include.
- DKIM: Generate and add the DKIM public key (TXT record) provided by Spryka so outgoing messages are cryptographically signed.
- DMARC: Publish a DMARC policy to instruct receivers how to treat unauthenticated mail from your domain and to receive reports. Start with a monitoring policy (p=none) and move to quarantine or reject after verifying results.
Why each matters:
- SPF helps ISPs confirm the email came from an authorized server.
- DKIM ensures the message wasn’t altered in transit.
- DMARC ties SPF/DKIM together and provides reporting so you can spot spoofing or configuration issues.
Practical Spryka steps:
- In your Spryka account, find the DNS records they provide for SPF and DKIM.
- After adding records, use Spryka’s domain verification tool to confirm authentication is correctly set up.
- Create a DMARC record like:
v=DMARC1; p=none; rua=mailto:[email protected]; ruf=mailto:[email protected]; pct=100
Then adjust p=quarantine or p=reject after monitoring.
3. Optimize Content for Deliverability
What’s inside your email affects spam filters. Good content increases reader interaction and reduces spam-trigger signals.
- Keep subject lines clear and not spammy. Avoid excessive punctuation, all-caps, deceptive phrasing, and overly promotional words (e.g., “FREE!!!”, “Act Now!!!”).
- Personalize but don’t overdo it. Use a real sender name and a consistent from-address (e.g., “Jane from YourCompany [email protected]”).
- Balance text and images. Image-only emails or very large images can trigger filters. Aim for a reasonable text-to-image ratio and include meaningful alt text.
- Include a plain-text version. Spryka can generate one automatically; ensure it’s readable and not just an HTML dump.
- Keep links clean and consistent. Avoid URL shorteners or redirect-heavy links; use your domain or Spryka’s link tracking domain if it’s reputable.
- Provide a clear unsubscribe link. Hiding the unsubscribe damages deliverability and can cause spam complaints.
Practical Spryka steps:
- Use Spryka’s subject line preview and A/B testing to test variations.
- Enable automatic plain-text generation and review it for quality.
- Use Spryka’s inbox preview to check how emails render across clients.
4. Warm Up New IPs and Domains Gradually
If you send large volumes or start with a new sending IP/domain, sudden high volume can trigger ISP throttling or blocks. Warming up builds reputation slowly.
- Start small and ramp up. For a new IP, send to your most engaged users first (top 1–5% engagement) and gradually increase volume over 2–4 weeks.
- Use consistent sending patterns. ISPs look for predictable behavior; sporadic spikes can be suspicious.
- Monitor feedback loops and complaints. Spryka should provide complaint metrics; address issues quickly (remove complainers).
- Consider using Spryka’s dedicated IP only when you can maintain consistent volume; shared IPs can be fine for lower-volume senders if the provider maintains good IP reputation.
Sample warm-up schedule (example for a dedicated IP):
- Days 1–3: 500–1,000 emails/day to most engaged list
- Days 4–10: increase by 50–100% daily, expanding segments
- Days 11–21: reach target sending volume, monitoring bounces/complaints closely
Practical Spryka steps:
- Coordinate with Spryka support if starting a dedicated IP — they can advise on warm-up.
- Use engagement segments to seed sends to high-quality recipients first.
5. Monitor Deliverability Metrics and Iterate
You can’t improve what you don’t measure. Track key metrics and respond quickly to trends.
Key metrics to watch:
- Delivery rate (emails accepted by receiving servers)
- Bounce rate (hard vs soft)
- Open and click rates (engagement)
- Complaint rate (spam reports)
- Unsubscribe rate
- Inbox placement (if you run seed tests)
How to act on data:
- If bounces rise: pause sends, analyze bounce types, remove faulty addresses.
- If complaints increase: review recent campaigns for misleading subject lines, send frequency, or poor targeting; remove complainants and consider re-permissioning campaigns.
- If open rates drop: test subject lines, sender names, or sending times; consider re-engagement campaigns for lapsed users.
- Use Spryka’s reporting to create automated alerts for spikes in bounce or complaint rates.
Practical Spryka steps:
- Set up dashboards in Spryka to show the above metrics.
- Export DMARC reports and review them weekly.
- Run periodic seed tests (send to a set of test addresses across ISPs) to check inbox placement.
