What is LoopNet CDX Mail?
LoopNet CDX Mail is LoopNet’s in-platform email tool. It lets agents send property announcements to contacts. The tool links listings to emails and tracks opens and clicks. CDX sits inside the CoStar family of products. Many professionals use it to reach investors and tenants. It is handy because it connects listings, marketing, and analytics. But the system has contact tiers and limits. When your list grows, you may need to upgrade to send to more people. That is when you consider the loopnet cdx mail upgrade for more than 500 contacts. The upgrade unlocks higher caps and extra features for larger lists.
Why LoopNet limits contacts to 500 by default
LoopNet sets limits to protect deliverability and system stability. Sending too many emails at once can harm sender reputation. Low-quality lists increase bounce and spam reports. These outcomes hurt every user on the platform. A default cap keeps new accounts from sending large, risky campaigns. The cap also nudges users to clean and segment lists. That improves open and response rates. When your business grows, the cap becomes a real obstacle. That is why LoopNet offers higher tiers. You should choose the loopnet cdx mail upgrade for more than 500 contacts only when your lists are clean and opt-in.
When you need the loopnet cdx mail upgrade for more than 500 contacts
You likely need the upgrade when your list exceeds 500 valid, opted-in addresses. If you run regional campaigns, investor alerts, or broker blasts, your list will expand fast. Also consider upgrading if you run frequent campaigns. High frequency plus high volume calls for more capacity. If you see many bounces or low opens, upgrade only after cleaning contacts. The loopnet cdx mail upgrade for more than 500 contacts helps send large property feeds. It also reduces manual splitting of lists. Upgrading saves time and helps consistent branding at scale. Think about upgrade timing and list health before you buy.
How to check your current contact count and list health
Start by exporting your contact list from your CRM or LoopNet. Open the export in a spreadsheet app. Remove obvious duplicates and empty rows. Look for bounced addresses and role accounts like info@ or admin@. Use simple tests to spot bad entries. Count only opted-in contacts. This gives you a real active-contact number. If that number is over 500, you may need the loopnet cdx mail upgrade for more than 500 contacts. Clean lists lower bounce rates and protect your sending reputation. Clean data also improves segmentation and targeting for specific property types.
Upgrade options and what to expect (features and limits)
When you upgrade, you get higher contact caps and richer analytics. You may also get better sending throughput and priority support. Plans vary by account type and region. Upgrades might include automated list imports and advanced segmentation. Some tiers offer API access or CSV import automation. Expect billing to reflect contact counts and send volume. Always ask support what counts as a billable contact. Some platforms count duplicates or suppressed addresses differently. If you need to send to thousands, confirm per-mail and monthly caps. The loopnet cdx mail upgrade for more than 500 contacts often unlocks these higher limits and pro features.
Step-by-step: how to request and complete the upgrade
First, log into your LoopNet/CoStar account. Go to your account settings or marketing tools. Look for CDX Mail or email settings. If an upgrade link appears, click it and review tier details. If you cannot find the option, contact LoopNet support or your account rep. Provide your current contact count and campaign needs. Support may ask for examples of recent sends. They may also ask about list hygiene practices. Once approved, follow billing and plan setup steps. After purchase, confirm the new limit in settings. If you see issues, contact support and keep a record of exchange.
Importing and managing large contact lists safely
When you import big lists, use CSV format and map fields cleanly. Include name, email, company, and role when possible. Avoid uploading unverified or scraped addresses. Always use opt-in lists for best results. Import in batches if the platform allows. This helps spot errors quickly and reduces bounce spikes. Maintain a clear unsubscribe and suppression list. Use tags or fields for property types, location, and investor vs. tenant. With the loopnet cdx mail upgrade for more than 500 contacts, organization matters more. Clean, segmented lists let you send targeted messages, improve opens, and lower spam complaints.
Deliverability: how to keep email landing in inboxes
Good deliverability begins with list quality and content relevance. Use a verified sender address tied to your domain. Authenticate mail with SPF, DKIM, and DMARC when possible. Avoid spammy words, long subject lines, and misleading headers. Send to engaged contacts first after an upgrade. Gradually ramp up volume to build reputation. Monitor bounce rates, opens, and spam reports. Remove cold contacts after a set period. If a campaign shows high bounces, pause and clean. The loopnet cdx mail upgrade for more than 500 contacts helps with volume, but deliverability depends on habits. Treat reputation as your top priority.
Compliance, permissions, and laws (CAN-SPAM, GDPR, and more)
Email laws require consent and clear opt-outs. In the U.S., CAN-SPAM sets rules for content and unsubscribe handling. International recipients may fall under GDPR or CASL. Keep records of opt-in sources and consent dates. Provide easy unsubscribe links and process requests quickly. Do not buy lists or send to scraped addresses. If you target EU contacts, ensure a lawful basis for processing. Keep data handling transparent and secure. The loopnet cdx mail upgrade for more than 500 contacts does not exempt you from laws. It is your responsibility to follow rules and protect recipient privacy.
Segmentation and targeting to get better results
Segmentation divides your list into relevant groups. You can segment by property type, role, geography, or past activity. Targeted lists get better open and click rates. Use tags like “investor,” “owner,” or “tenant” to refine sends. Test subject lines and messaging per segment. Try A/B tests for offers, images, or calls to action. When you upgrade with loopnet cdx mail upgrade for more than 500 contacts, segmentation becomes a major lever. It helps reduce wasted sends and lowers complaints. Plan your segments before importing large lists to save time and improve outcomes.
Tracking, reporting, and using analytics to improve campaigns
After sending, review open rates, click rates, and conversion metrics. Look at which links get clicks and which listings draw interest. Track which segments reply or request more info. Use this data to refine future sends and property listings. Export reports to your CRM for follow-up and lead scoring. Keep an eye on unsubscribe and spam complaint trends. If a segment shows poor performance, clean or re-engage it. The loopnet cdx mail upgrade for more than 500 contacts usually includes more robust reporting. Use those features to make data-driven decisions that increase leads and saves time.
Real example: how a small broker scaled without pain
I once worked with a broker who had 300 contacts and steady growth. Within months, the broker reached 1,200 names from past deals and investor lists. They first cleaned the list and removed old bounces. Then they chose the loopnet cdx mail upgrade for more than 500 contacts. They imported in batches and used segmentation by property class. They sent a warm-up schedule over two weeks to build reputation. Opens rose and inquiries doubled. The broker tied responses to a CRM and followed up within 48 hours. That small process change turned a messy list into a reliable lead channel.
Alternatives and integrations: when to use other email tools
LoopNet CDX Mail works well for property blasts. But some users prefer specialized email platforms. Mailchimp, SendGrid, or a CRM-based SMTP option can offer advanced automation. Integrations let you sync contact lists and track replies. If you need advanced templates or lifecycle automation, consider external options. Use LoopNet for listing visibility and an external tool for deep nurture flows. If you choose an outside provider, ensure you still follow LoopNet rules for listing mentions. The loopnet cdx mail upgrade for more than 500 contacts is right for many, but a hybrid approach can fit complex workflows.

Frequently Asked Questions
1) How long does the loopnet cdx mail upgrade for more than 500 contacts take to activate?
Activation time varies by account and support load. In many cases, upgrades process within a business day. Some accounts require manual review and take longer. Have your contact counts and sample campaigns ready. This speeds verification. If billing is required, clearing payment can add time. Keep logs of your support requests and confirmations. After activation, confirm new limits in account settings. If you do not see the change, contact support again with reference numbers. Plan campaigns with a buffer when you expect an upgrade.
2) Will upgrading harm my sender reputation or deliverability?
Upgrading itself does not harm reputation. What matters is list quality and sending behavior. Send to clean, opt-in contacts. Ramp up sends slowly and monitor metrics. Remove hard bounces and repeated non-openers. Avoid large cold blasts to raw lists. Use authentication like SPF and DKIM where possible. Follow CAN-SPAM and other laws. If you follow these steps, the loopnet cdx mail upgrade for more than 500 contacts will let you scale without damaging deliverability.
3) Can I import contacts from my CRM after the upgrade?
Yes, most users import from CRMs using CSV export and import. Map fields like name, email, company, and tags. Some plans support API or automated sync. Import in batches to catch mapping issues early. Keep a suppression list to prevent duplicate sends. Always re-check consent flags before importing. If you use a third-party integration, test a small campaign first. The loopnet cdx mail upgrade for more than 500 contacts supports larger imports, but careful mapping matters.
4) What are best practices for unsubscribes and suppression lists?
Make unsubscribe links easy to find and work well. Process unsubscribe requests immediately. Keep a central suppression list for bounces and complaints. Do not re-add suppressed emails without fresh consent. Document how you collect consent and store opt-in dates. Regularly export suppression lists for backups. This reduces legal risk and protects deliverability. Treat unsubscribe handling as a core process, not an afterthought.
5) Are there extra costs for API access or automated imports?
Costs vary by plan and account. Some upgrades include API access and larger imports. Others charge extra or require an enterprise plan. Ask LoopNet or your account rep for details. Clarify which features are included and which cost more. Confirm how contacts are counted for billing. Getting a clear price sheet avoids surprises. If budget is tight, consider staged upgrades or hybrid solutions with external email platforms.
6) How should I re-engage cold contacts after upgrading?
Start with a re-permission campaign. Send a short message asking if they want to stay on your list. Offer clear value like market updates or exclusive listings. Use simple subject lines and a clear call to action. Track who re-opens and clicks. Move engaged contacts to active segments. Remove those who don’t respond after a re-engagement sequence. This cleans your list and boosts future performance. The loopnet cdx mail upgrade for more than 500 contacts becomes much more effective with engaged recipients.
