Migration Guide
The complete guide to migrating your email sending from Constant Contact to dedicated IPs — with full IP warming support, zero downtime, and measurable inbox placement improvements.
Migrating from Constant Contact to Dedicated Infrastructure
Constant Contact is a small business-focused email marketing platform. It works well at lower volumes and for teams that want managed sending without infrastructure decisions. But senders who reach a certain scale — or who've experienced blacklisting, shared IP contamination, or deliverability plateaus — find that the lack of IP isolation and control becomes the bottleneck. This guide covers the complete migration process from Constant Contact to dedicated email infrastructure.
Quick facts: Constant Contact vs. dedicated infrastructure
| Feature | Constant Contact | Cloud Server for Email |
|---|---|---|
| IP type | Shared with thousands | Dedicated — yours only |
| IP reputation control | None — shared pool | Full — isolated per client |
| Blacklist monitoring | Basic or none | 50+ lists, every 4 hours |
| Sending volume visibility | Aggregate only | Per-IP, per-pool detail |
| IP warming | Auto/shared | Guided, per-use-case |
| ISP postmaster access | Limited | Full Postmaster Tools access |
| PowerMTA / Acelle / MailWizz | Not available | Available |
| Custom PTR records | No | Yes — per IP |
Why senders leave Constant Contact
The most common reasons senders at 100K–2M emails/month outgrow Constant Contact:
- Constant Contact uses shared IP infrastructure with limited deliverability control
- No ability to configure custom DKIM — uses Constant Contact's signing infrastructure
- Deliverability support is limited to general best practices rather than technical monitoring
- Platform is designed for simplicity, limiting technical configuration options for advanced senders
- Per-contact pricing becomes expensive as lists grow
Key benefits after migration
Authentication control
Your own DKIM keys and PTR records
IP isolation
Dedicated IPs — your reputation is entirely yours
Deliverability insight
Full Postmaster Tools access, blacklist monitoring, SNDS data
Predictable cost
Flat monthly rate regardless of list size or send frequency
Migration process: 3–4 weeks
Export your Constant Contact data
Export all contact lists as CSV from the Contacts section. Export unsubscribers separately — these must be honored after migration.
Set up your infrastructure
We configure dedicated IPs, MailWizz or Acelle deployment, monitoring, and SMTP credentials within 24–48 hours.
Configure DNS
Add DKIM TXT records for your sending domain, update SPF, and set up DMARC. Constant Contact was likely handling authentication — you now take full control.
Import contacts and suppressions
Import all contact lists and suppression lists. Map your Constant Contact list segments to your new platform's list structure.
Warm-up campaign
Begin with contacts who have opened or clicked within the last 60 days. This group generates the positive signals that build IP reputation fastest.
Full transition
After 4–6 weeks of warming, your IP reputation should be stable. Complete the transition and discontinue Constant Contact sending.
