Real-world delivery proof

Live ESP validation (Brevo) showing delivered, bounces, blocks, and inbox events for MyCQL-exported data.

Summary (production sample)

613 emails sent via Brevo (live SMTP)
100% delivered
0% hard bounces / 0% soft bounces
0% blocked / 0% spam complaints
Engagement events observed (opens, clicks, unsubscribe)

Important: This page shows real sample results. Deliverability depends on sender reputation, warm-up, content, and compliance. No platform can guarantee identical results at unlimited scale.

Brevo statistics: 100% delivered, 0% bounced — **Brevo Statistics** — delivered, bounces, blocks, and complaints (live campaign).

Brevo real-time events: opened, proxy, unsubscribed — **Brevo Real-time** — inbox events (opens, proxy loads, unsubscribe) confirming delivery to real recipients.

Germany delivery proof (controlled test)

This is a small, controlled send using MyCQL-exported data. The goal is to prove real inbox placement with measurable engagement (opens + clicks), not just “sent”.

49 events (Brevo real-time)
49 delivered (100%)
34 trackable opens (~69%)
33 clicks (~67%)
1 bounce (soft bounce) — typically temporary (greylisting, mailbox limits, server delays)

Germany test: Brevo real-time summary (delivered, opens, clicks, bounce) — **Germany — real-time summary** (delivered, opens, clicks, bounce).

Germany test: Brevo recent activity (opens and clicks) — **Germany — live engagement** (opens and clicks) confirming delivery to real recipients.

Germany test: Brevo logs showing soft bounce — **Bounce transparency** — sample log showing a **soft bounce** event. Soft bounces are common and usually temporary.

UAE Test (Balanced Mode) — What this means

This send was performed using Balanced mode (the MyCQL default). Balanced is built for maximum quality + reputation safety. Layer-4 validation remains active and strict, which is why deliverability is usually extremely clean in this mode.

0 bounces in this window = inboxes were accepted by destination servers (provider-level success).
Low clicks / opens here does not mean “bad leads”. Engagement depends heavily on timing, offer, and message quality.
In this example below, the send time is likely outside normal working hours in the (UAE example) — many recipients are offline / asleep, so clicks and opens stay low.

Brevo real-time statistics — aggressive Layer-4 sending

Marketer tip (to improve opens & replies)

Schedule sends for the recipient’s local business time (UAE): 09:00–12:00 or 13:00–16:00.
Avoid late-night sending unless you’re testing or warming up.
Run A/B tests: subject line + first sentence matter more than any tool.

When is the best time to send?

Deliverability and engagement improve when you send during a high-response window in the recipient’s local time. Our controlled tests are intentionally sent in clean windows (no spikes) to avoid provider suspicion and maximize inbox placement.

Weekdays generally outperform weekends for B2B.
Morning → early afternoon (local time) often yields better opens/clicks.
Avoid huge bursts from a cold domain — warm-up matters.
Timing helps, but timing alone is not enough: you also need clean data + good reputation.

The “diamond” formula: 4‑Layer verification + domain reputation

Layer 1 — Syntax & structure

Invalid formats, domians, DNS/MX... are rejected before processing.

Layer 2 — Smart Engagement Filtering

Filters out addresses that are technically valid but statistically unlikely to engagee.

Layer 3 — Risk & pattern detection

Disposable, role-based, trap-like and risky patterns are excluded.

Layer 4 — Live deliverability intelligence

Recheck + Suppression + provider behavior rules reduce bounces and avoid unnecessary retries.

Diamond result: When you combine clean verified data, the right send timing, and a good domain reputation, you get the strongest outcome: delivery + inbox placement + engagement — not just “sent”.

How to interpret this proof

Delivered means destination servers accepted the emails (no provider-level rejection).
Hard bounce is usually permanent (non-existent inbox).
Soft bounce is often temporary (busy server, greylisting, mailbox limits).
Opens/clicks confirm real inbox placement and real recipient interaction.
Unsubscribe events are a trust signal: they prove messages reached real humans with opt-out options.
