Contact Us

A contact, or subscriber, refers to a unique individual in your SenderWiz account. In simpler terms, each email address you add is counted as one subscriber.

Unlike many other providers, SenderWiz has no limit on the number of contacts you can add, regardless of the package you choose. This gives you the flexibility to scale your email campaigns as needed.

Yes, it’s designed to be user-friendly! With intuitive navigation and a step-by-step walkthrough, you can start sending your first email campaign in under 5 minutes, even if you’re new to email marketing.

When you integrate a third-party email service provider (ESP) with SenderWiz, bounce and complaint reports are automatically synced through our seamless API integration. This ensures that your account is always up-to-date with the latest data.

If you create your SMTP using SenderAI, the platform will automatically manage bounce handling for you. Any bounced emails or complaints will be detected and processed without manual intervention.

In either case, all bounced emails and complaints are promptly added to your blacklist to help protect your sender reputation and ensure your campaigns reach the intended recipients.

We accept all major credit and debit cards.

With our SenderAI feature, you can create your own SMTP server using a VPS or dedicated server with a few IPs and domains. This is a cost-effective way to send large volumes of emails without relying on external services.

On the other hand, external delivery servers like Amazon SES or Mailgun provide advantages such as enhanced deliverability, scalability, and seamless integration. These services are optimized for high-volume email sending and can help reduce the risk of issues like blacklisting that may occur with self-managed SMTP servers.

• Authenticate Your Emails: Proper SPF, DKIM, and DMARC configurations (automatically handled by SenderWiz).
• Use High-Quality Lists: Ensure verified, engaged recipients to reduce bounces and complaints.
• Maintain a Good Reputation: Clean your lists regularly and manage IP/domain reputation.
• Optimize Email Content: Avoid spammy words, use clear subject lines, and send valuable content.
• Warm-Up IPs: Gradually build trust by sending to engaged recipients.
• Send Slowly: Start small, then scale up to avoid triggering spam filters.
• Use External Servers: Services like Amazon SES, Mailgun, or SparkPost offer better scalability and deliverability (extra costs may apply).

By implementing these practices, you can greatly enhance delivery rates. Our platform automates authentication, IP warming, and integrates with external providers to streamline the process, so you can focus on your campaigns.

Yes, you can send cold emails, but it’s important to follow best practices to ensure high deliverability and compliance with laws like the CAN-SPAM Act or GDPR. This includes personalizing your messages, ensuring you have a valid opt-out option, and avoiding spammy language. It’s also crucial to warm up your IPs and domains to build trust with email providers, as well as sending emails in small batches initially to avoid being flagged as spam.

To set up your own SMTP server, you’ll need:

• VPS or Dedicated Server: A reliable server with sufficient resources (CPU, RAM, storage) to handle your intended email volume.
• Additional IP Addresses and Domains: Multiple IPs and domains to scale your email sending capacity. The required number depends on your email sending plan and daily volume.

For example, the Enterprise Plan allows up to 20 IPs and 20 domains, supporting up to 100,000 emails per day.

Note: Ensure your server provider permits mailing activities and has the necessary ports (e.g., Port 25) open.
