Yes. BulkEmailChecker uses SMTP verification to check if a cogeco.ca mailbox exists without ever delivering an email. Our system connects to the domain's mail server, performs an SMTP handshake, and queries the mail server to confirm whether the recipient address is valid. This process is completely invisible to the email recipient and does not affect your sender reputation.
Sending to invalid email addresses causes hard bounces, which directly damage your sender reputation. Internet Service Providers (ISPs) and email providers track your bounce rate, and if it exceeds 2%, your emails may start landing in spam folders or get blocked entirely. Verifying cogeco.ca addresses with BulkEmailChecker before sending prevents bounces and keeps your deliverability high.
BulkEmailChecker's bulk verification service lets you upload a CSV or TXT file containing thousands of cogeco.ca email addresses and verify them all at once. Each address goes through 30+ verification checks including syntax validation, DNS/MX lookup, SMTP verification, disposable domain detection, and spam trap identification. Results are typically ready within minutes and can be downloaded as a clean, verified list.
Email verification is the process of confirming that an email address is real, properly formatted, and capable of receiving messages. It matters because sending to invalid addresses causes bounces, damages your sender reputation, wastes marketing budget, and can get your sending IP blacklisted. BulkEmailChecker verifies addresses at the SMTP level, the most accurate method available, ensuring your emails reach real people.
MX (Mail Exchange) records are DNS entries that specify which mail servers are responsible for receiving email for a domain. When you send an email, your mail server looks up the recipient domain's MX records to find where to deliver the message. If a domain has no MX records, it cannot receive email. BulkEmailChecker checks MX records as part of every verification to confirm the domain is configured for email delivery.
A catch-all (or accept-all) domain is configured to accept email sent to any address at that domain, regardless of whether the specific mailbox exists. This makes it harder to verify individual addresses because the server always responds positively. BulkEmailChecker detects catch-all configurations and flags them in verification results so you can make informed decisions about sending to those addresses.
Yes. BulkEmailChecker offers a real-time email verification API that you can integrate into signup forms, CRM systems, lead capture tools, and any application that collects email addresses. The API validates addresses at the point of entry, blocking invalid, disposable, and risky emails before they enter your database. Integration takes just a single API call with response times under 3 seconds.
