Not really. Almost all modern marketing tools today are cloud-based and work through your browser. Of course, the disadvantage is that all your data is stored on another company’s server. Reputable providers are usually certified accordingly and process the data entrusted to them in accordance with GDPR. A cloud-based solution also has numerous advantages. For example, you don’t have to install everything, you can just work directly in the browser. You also use the provider’s email server to send your newsletters, which is ideally configured for sending bulk emails.
