The philosophy behind every recommendation we make.
Absolute transparency in sender reputation reporting and white-hat strategy implementation.
Leveraging machine learning to predict filter behavior and optimize sequence timing.
Our metrics are your metrics. We only win when your open rates reach peak performance.
Mailing advice encompasses technical setup (SPF, DKIM, DMARC), content optimization, and sender reputation management to ensure your emails reach the primary inbox rather than the spam folder.
Improvement comes through a multi-layered approach: cleaning your lists, warming up new IPs, personalizing content to drive engagement, and monitoring ISP feedback loops consistently over time.
Yes, but it varies by audience. Generally, B2B engagement peaks mid-morning on Tuesdays and Thursdays. We use behavioral data to determine the specific "golden hour" for your list.
Absolutely. Our team provides dedicated consulting sessions, infrastructure audits, and fully managed deliverability monitoring tailored to your specific volume and goals.
IP warming is the process of gradually increasing your sending volume from a new IP address. ISPs need time to evaluate your sending patterns — jumping straight to high volume triggers spam filters. A structured 4–6 week warm-up plan builds trust and secures long-term inbox placement.
Spam traps are email addresses used by ISPs and blacklist operators to identify senders with poor list hygiene. They come in two forms: pristine traps (never valid addresses) and recycled traps (previously valid addresses). Avoid them by never purchasing lists, using double opt-in, and running regular list validation to remove stale contacts.
These three DNS-based authentication standards form a security chain. SPF specifies which servers are allowed to send on your domain's behalf. DKIM adds a cryptographic signature to each email to verify it hasn't been tampered with. DMARC ties them together and tells ISPs what to do if either check fails — reject, quarantine, or allow. All three must be properly configured for optimal deliverability.
Industry averages vary, but 20–35% is considered healthy for most sectors. To lift your rate: segment your list by behavior and interest, personalise subject lines, test send times, and re-engage or sunset inactive subscribers. High engagement signals to ISPs that your emails are wanted, which in turn improves future deliverability.
First, identify which blacklist(s) you are on using tools like MXToolbox. Then diagnose the root cause — spam complaints, high bounce rates, or spam trap hits. Fix the underlying issue, clean your list, and submit a delisting request with evidence of remediation. Most reputable blacklists will delist within 24–72 hours once the source issue is resolved.
Yes, significantly. Spam filters analyse content for trigger words (e.g. "free", "guaranteed", "urgent"), excessive HTML, broken links, misleading subject lines, and poor text-to-image ratios. A clean plain-text structure, clear unsubscribe links, and personalised content all contribute positively to filter scores and engagement metrics.
For active senders, a quarterly deep clean is recommended. This means removing hard bounces immediately after each send, suppressing contacts with no engagement in 6+ months, and running your list through a verification service annually. Regular hygiene keeps your sender score high and reduces the risk of hitting spam traps.
