There is a real difference between "Can I send you an email?" and "I can send an email". And we're not just talking about which questions to ask your prospective subscriber.
If you want to mention, WordTask defines the term "may" as a permission or as an option, while "ability".
The first question in email marketing … "Can I send an email?" is the key question you ask your prospective subscriber when he gets permission to send him an email. This is where you have to be very clear about what you are asking for your permission and you must be very clear about what you are going to give you permission.
The "I can send you an email" is a completely different story. However, the actual ability to transfer the email is still a small license. Not so much the license request … the "Can it?" because no one really can ask for permission … but you can try to test whether you actually receive the email from the "basket" to the "buyer's basket" in the desired basket.
This is the most technical aspect of e-mail marketing, and this can be a lot more complicated.
E-mail marketing "may" consists of a prospective subscriber having the right software to receive your email in the format you are planning. … and … (the part about knowing that you will get permission without permission without saying "Mom?") (can) get your content and layout through the many spam licensees the filters currently used by Internet service providers, and additional filters added by the prospective subscriber.
The first part of "Possible …" in the sense that the subscriber can actually read what he sends is somewhat easier than the computer operating systems and the sof. The tware updates now allow most e-mail users make reading HTML, PDF and text. However, this is certainly not 100%, so it is part of "Can I send you emails?" Questionnaire: "What kind of emails do you want to receive?" so you will know what you can read on your computer and what you want.
The second part of the "I Know" (physical delivery capability) includes … to allow … or to add to the list of acceptable contacts and confirm your subscription that you will not receive your emails automatically sent to "spam".  Now that you've achieved it, the hardest part of the "Get the Email" is the hardest obstacle. And frankly, it's best for experts. Especially if you are developing a great e-mail list quickly. Experts in the delivery of spam filters are e-mail marketing services that act as agents, and have developed "contact" with Internet service providers. They know and understand which words, phrases, graphics, and other test criteria may cause messages to be "spam" and block them before they arrive.
