Our IP/domain is blacklisted. What should we do?
Notify Inboxroad Support immediately (we monitor major lists and will investigate).
We submit delisting requests where applicable (we own the IPs and handle provider communication).
To maintain continuity, we may assign a new clean IP.
You must fix root causes (list hygiene, content/links, easy unsubscribes, check for compromises). Delisting is effective only if issues are resolved.
Why do I need a landing page?
ISPs and security tools evaluate URLs in emails. A relevant, professional landing page signals legitimacy, aligns expectations between email and destination, and builds domain reputation. Linking to suspicious or irrelevant sites harms reputation and increases spam-folder risk.
What practices help avoid soft bounces and improve inbox delivery?
Maintain list hygiene
Remove inactive/unengaged,
Segment for relevance
Keep a consistent sending pattern (avoid spikes)
Optimize content
Concise, balanced text-image ratio(common recommendation today, the ideal ratio is often cited as 60% text to 40% images), avoid oversized attachments
Monitor bounces to suppress repeatedly problematic addresses.
How can we check the “rating” of our subject line and email body?
There is no single score that guarantees delivery. Use spam-word checkers to flag risky terms and inbox placement testing (seed tests) to see if you land in Inbox/Promotions/Spam and to surface issues with content or links. Follow best practices: personalize content, use clear subjects, keep a good text-to-image ratio(common recommendation today, the ideal ratio is often cited as 60% text to 40% images), and ensure clean HTML.
My email provider says I’ve been “Blacklisted by the Recipient’s Server” due to a poor reputation or a history of spam complaints. Is there a way to fix this?
Yes, a poor sender reputation is not a permanent state and can be improved through a focused and disciplined approach. While being blacklisted by a recipient’s server can be a significant challenge, it is a signal that key aspects of your email sending practices need to be reviewed.
To rebuild your reputation, you must proactively address the root causes of the issue. This involves a comprehensive audit of your email quality and sending behavior, including:
Content and Message Quality: Review the content of your emails for common spam triggers, such as overly promotional language, excessive use of all-caps or exclamation points, and irrelevant subject lines.
Header and Technical Configuration: Verify that your email headers, links, and all technical settings (including SPF, DKIM, and DMARC records) are correctly configured. Poorly configured records can make your emails appear suspicious.
Engagement Metrics: Focus on sending relevant, valuable content that encourages engagement (opens and clicks) and minimizes negative actions (spam complaints and unsubscribes).
Why is it so important to send only to active subscribers?
ISPs and spamfilters like Spamhaus monitor engagement. Opens, clicks, and replies raise reputation and inbox placement. Inactive recipients depress engagement and can trigger spam filtering. Cleaning your sending base regularly is essential.
Why am I seeing low inboxing at Gmail even though my delivery rate is 100%?
Delivery means Gmail accepted the messages; inboxing is where they land (Primary, Promotions, Spam). With a new domain and very low volume (e.g., ~500 emails), Gmail has little or no reputation for you, so early sends often go to Promotions or Spam.
What to do:
Warm up gradually over weeks/ Follow our warmup schedule to ensure good domain reputation
Always review your sending base it may occur that some of recipients will decrease your domain reputation which will cause heavier bounces. Be sure to avoid receivers that are listed below:
Non-existent Addresses: The email address may have been valid in the past but has since been deactivated, closed, or abandoned.
Fake or Disposable Addresses: The address might be a temporary, single-use email created to sign up for something without receiving follow-up emails.
Spam Traps: The email address is a “spam trap,” which is an address intentionally created by internet service providers (ISPs) to catch spammers. Sending to a spam trap instantly damages your reputation and can get your IP address or domain blacklisted.
Verify content
clear subject
text-forward template
avoid spammy language or shady links
keep good text to image ratio
Historically, and still a common recommendation today, the ideal ratio is often cited as 60% text to 40% images. Some stricter sources even suggest 80% text to 20% images.
Never send an email that is just one large image. This is the biggest red flag for spam filters and is terrible for accessibility and user experience.
