FAQs - SenderWiz
We've compiled a list of common FAQs to help you navigate through the various aspects of email sending.
Can I upgrade, downgrade, or cancel my subscription anytime?
Yes, you can upgrade or cancel your subscription at any time.
However, downgrading is not possible due to limitations such as preserving your data, retaining existing SMTP configurations, and other technical constraints that cannot be reversed.
Do you send emails on my behalf?
No, SenderWiz does not send emails on your behalf. Instead, we provide a powerful platform that allows you to send emails directly from your own email marketing setup.
You have full control over your email campaigns, including the sender address, domain, and content.
However, if you prefer to hire experts to manage your email campaigns, you can contact us, and our team will be happy to assist you.
Can you guarantee my emails will land in the inbox?
While we provide the tools and best practices to optimize email deliverability, the final decision lies with inbox providers (like Gmail, Yahoo, Outlook, and private domains).
Factors such as spam filters, user behavior, and reputation systems are beyond our control.
However, if you're using our SMTP, you can change your IPs or domains through the SenderAI feature if they are blacklisted or underperforming.
You can also enhance deliverability by integrating with external providers like Amazon SES, Mailgun, or SparkPost.
By following our recommended strategies, we can significantly improve your chances of reaching the inbox.

Is there a limit to the number of contacts I can import?
No, there is no limit to the number of contacts you can import into the platform. You can import as many contacts as needed without restrictions.
What is SMTP?
SMTP stands for Simple Mail Transfer Protocol. It’s a system that helps send emails from one server to another over the internet.
You can think of it like a postal service for emails—when you send an email, SMTP helps deliver it to the recipient's inbox.
In the context of SenderWiz, SMTP allows you to send emails through your own server. You can use SenderWiz to set up your own SMTP server, which gives you control over your email sending process.
Our SenderAI feature even helps you create multiple SMTP servers instantly, which is great if you want to increase your email sending capacity or manage different sending domains.

Can I create my own SMTP?
Yes, you can create your own SMTP server with SenderWiz, which gives you much more control over your email marketing.
Using our SenderAI feature, you can instantly generate as many SMTP servers as you need.
This flexibility is especially useful if you need to scale your email marketing efforts or manage multiple domains for different campaigns.

Can I replace my IPs/domains?
Yes, you can replace your IPs and domains. This is important because if your email sending practices aren’t good or your IP gets blacklisted, your emails might be marked as spam.
With SenderWiz and our SenderAI feature, you can easily change your IPs and domains. This helps you avoid problems with deliverability (getting your emails to the inbox) because if one IP or domain gets blacklisted, you can switch to another one to keep sending emails without issues.

What is IP/domain blacklisting?
IP or domain blacklisting happens when an email service provider or spam filter marks your email address, domain, or IP as suspicious. This usually happens if you're sending a lot of unsolicited emails or if recipients mark your emails as spam.
Once blacklisted, your emails are more likely to be sent straight to the spam folder, or worse, blocked entirely.
With SenderWiz, you can prevent this problem by regularly updating and rotating your IPs and domains using SenderAI. This means you’re less likely to get blacklisted, keeping your email deliverability rates high.
How many emails can I send per SMTP (or per IP/domain)?
The number of emails you can send depends on how many IPs/Domains you have.
Each IP has a limit to how many emails it can send to avoid being flagged as spam. At SenderWiz, we set a limit of 6 emails per minute per IP to help prevent your IP from being blacklisted.
For example, if you have 10 IPs, you can send 6 emails per minute per IP, which means 60 emails per minute. Over an hour, that adds up to 3600 emails, and in a full 24-hour day, you can send 86,400 emails.
This flexibility lets you scale your email campaigns easily. If you want to send more emails, just add more IPs and SMTP servers through SenderAI.

What are external delivery servers?
External delivery servers are third-party email services that help you send your emails. Some examples are Amazon SES, Mailgun, and SparkPost. These services handle the technical side of email delivery, so you don’t have to worry about managing your own SMTP servers or IPs.
With SenderWiz, you can either use our SMTP service or connect your external delivery servers like Amazon SES or Mailgun for even higher deliverability rates. These services often have larger infrastructures and better reputation management to help ensure your emails land in the inbox.
Note: External delivery services come with an additional cost, often based on the number of emails sent or volume of traffic.
How is SenderWiz different from other email service providers like Mailchimp?
SenderWiz is different because it gives you complete control over your email sending. While services like Mailchimp come with limitations on customization and flexibility.
SenderWiz, on the other hand, offers much more flexibility and control over your email campaigns. Here's how:
Unlimited SMTP Servers You can create as many SMTP servers as you need, allowing you to manage your sending infrastructure according to your specific needs. Unlike Mailchimp, which uses its own delivery servers, SenderWiz lets you choose or create your SMTP servers, giving you more control over your email flow.
Manage and Rotate IPs/Domains Easily with SenderAI Using SenderAI, you can easily manage and rotate your IPs and domains to maintain high email deliverability. This feature helps protect your sending reputation by ensuring that if any IP gets blacklisted, you can replace it instantly without disrupting your campaigns.
High-Volume Sending Without Restrictions With SenderWiz, you can send high volumes of emails without worrying about being flagged as spam. Unlike other services that might impose daily or hourly sending limits, SenderWiz provides flexibility by allowing you to send as many emails as you need, depending on the number of SMTP servers, IPs, and domains you have.
No Subscriber-Based Charges Unlike Mailchimp and similar providers, where you're charged based on the number of subscribers or contacts in your list, SenderWiz charges based on your email usage and plan. There's no additional cost based on the number of contacts you have, making it more cost-effective for businesses of all sizes.
Low-Cost with Fewer Restrictions SenderWiz is a more affordable choice, especially for businesses that need to send large volumes of emails. Since SenderWiz isn't based on the number of contacts or subscribers, you avoid the costly price hikes associated with platforms like Mailchimp, which often charge higher fees as your subscriber list grows.
Create and Choose Your Delivery Server You have the option to either use SenderWiz’s SMTP servers or integrate your preferred external delivery servers such as Amazon SES, Mailgun, or SparkPost. This level of flexibility ensures you get the best deliverability options for your needs. Other providers typically have their own restricted delivery infrastructure, limiting your options.
Ideal for Cold Mailing SenderWiz is perfect for cold emailing campaigns, especially for businesses that need to send emails to a large number of recipients without restrictions on list size or sending limits. The platform allows you to manage multiple domains, IPs, and SMTPs, giving you the flexibility to warm up new domains or scale your campaigns without hitting walls.
Summary: SenderWiz is the ideal choice for businesses looking for a customizable, cost-effective, and scalable email solution. Unlike Mailchimp and other similar providers that impose heavy restrictions and high fees based on subscribers, SenderWiz lets you manage your email infrastructure the way you want—create unlimited SMTP servers, choose external delivery servers, and replace your IPs or domains when necessary. Plus, there’s no restriction on the number of contacts or subscribers, making SenderWiz the perfect tool for high-volume or cold mailing campaigns.
