MailsBroadcast sent emails as fast as your ISP mail server can accept them. Therefore, speed of sending emails is not due to the program itself...

Controllable and uncontrollable factors that can affect the speed of broadcasting emails.

The speed of broadcasting emails depends on various controllable and uncontrollable variable factors. It does not matter whether you are using a 56K, ISDN, DSL, ADSL Network or Cable Internet connection.

Only by optimizing the controllable variables and operating within optimal uncontrollable factors, will it allow you to maximize the speed of broadcasting email messages.

MailsBroadcast send emails continuously in groups of 50 (default setting) to your ISP mail server which in turn depend on how fast your ISP mail server ability can cache them for distribution. Therefore, the speed of sending emails will be affected by some of these factors:

(a) You connection speed -- ie: 56.6 dial-up, 64/128 ISDN 256/512 DSL/ADSL, Cable connection, etc.

(b) The upload speed allowed by your ISPs, you may be connected at 512 with an ADSL line but your ISP may not allow you to upload at that speed.

(c) The Internet throughput--meaning that just like peak hour traffic, the highway maybe having 8 lanes but all the cars are going in the same direction and traffic simply slowed down to a crawl.

(d) Your ISP mail server--under maintenance, busy peak hour, etc.

About TCP/IP and mail server port numbers? It is a number between 1 and 65535 which identifies to the receiving computer what function you want to perform

Speed of broadcasting emails depends on various factors such as; Internet connection bandwidth or throughput, ISP mail server (your mail server) and connection device like 56Kbps (V.90 or V.92), ISDN (64kbps or dual 128kbps), 256/512Kbps DSL/ADSL, or broadband Network/Cable T1 or T3 connection, etc.

Throughput? The outgoing & incoming datagram Bits.Bytes between your computer, ISP connection and the Internet network.

ISP Bandwidth is the bandwidth that your Internet Service Provider offers and it can affect your modem speed. Your ISP may have a T1 (1.544Mbps) or E1 (2.048Mbps) to the back-bone of the Internet, but this is of little use if they only feed your POP (Point-of-Presence) with a 64Kbps data line and also that you may not be the only user being on-line at the same time.

Therefore, when you are connected to your POP you ultimately share bandwidth with all other users that are also connected to it at the same time. For example: If two users' modems connect to their ISP modems at 56Kbps and if the POP is served by a 64Kbps data line, then, they both share this 64K bandwidth.

Note: Different ISP provide different up-load and download speed--meaning that having a 256/512Kbps DSL or 480Mbps USB 2.0 High Speed or Full Speed 12 Mbps 2.0 USB ADSL download does not mean that you can up-load at the same speed, check it up with your ISPs.

It also depends on whether your motherboard support USB 2.0 (1.1 device)  Full Speed device or the USB 2.0 High Speed--meaning that if you have a ADSL 2.0 USB Full Speed Modem running on USB 1.1 then you only get 12 Mbps

Emailing speed can
be as slow as
500 or 5,000 text message per hour (depending on message size) using a 56K or ISDN, DSL at the lower end and for ADSL, Network or
T1 (1.544Mbps) Cable connection, may even send up-to 250,000 emails per hour--depending on the Internet connection throughput and computer mail server system capability.

Below here are some variable factors that will affect the speed of broadcasting emails and can't be easily controlled. Therefore you need to work within it to maximized the speed of broadcasting emails.

1. Internet peak hour, for example: in the evening, (like morning rush hours) too many people are on-line at the same time and your ISP network connection is congested although you are connected at 56kbps/516kbps or higher.

You won't be able to get maximum throughput--the outgoing and incoming datagram is slowed down between your computer, ISP Internet connection and the Internet network.

Just like lunch hour, because of the high number of customers to be served by limited number of waiter, more time is required before your turn to be served by the waiter/cook.

2. Recipients ISP mail server, busy and slow to process all the incoming and outgoing mails--usually during peak hours.

3. Your ISP mail server, busy and slow to process all the incoming and outgoing mails--usually during peak hours. If it is always consistently inefficient, change your ISP.

4. Your own mail server, slow microprocessor, not well maintained, inefficient and used for other functions.

5. Your mail server program, if you are broadcasting directly to your email recipients, it depends on the type of mail sever program being used, ie: single or multi thread.

Single thread, send email one at a time and after the recipient ISP mail server have accepted the email, will it proceed to send the next one. Multiple threads send 10 or more emails simultaneously. Having a fast mail server program with poor connection throughput won't speed up sending emails.

6. Type of Internet connection, irrespective of connecting device used--quantitatively--mailing speed will be affected in combination with above mention factors.

A powerful car can't go very much faster than a small car--driving along a congested peak hour freeway--both are affected.

What if, there are no restrictions on the freeway, how are you going to max-out--if your car (big or small) is not tuned, to take advantage of it?

A. Avoid using your PCs for multi-tasking while broadcasting email, to prevent using-up resources and slow-down the mailing process.

B. Avoid using your mail server computer for other network functions, to prevent using-up resources and slow-down the mailing process.

C. Faster computer microprocessor system with efficient hardware resources like; RAM, SCSI or 7,200 RPM hard-disk, etc. can speed-up broadcasting emails.

D. Broadcasting from your computer as dedicated mail server with a multi-thread mail program will increase its mailing capability.

E. Optimizing your computer to whatever type of Internet connection being used, can maximized throughput and increased mailing capability.
Speedup  MaxMtu  Bits.Bytes  UART

56.6 kbps V92 compliance modem (if supported by your ISP) allow you maximum up-load speed and have optimum broadcasting emails.

ISDN modem setting should be dual line 128 kbps to maximized broadcasting emails.

DSL, ADSL, Network or Cable connections are also subject to "throughput" problem because your ISP or IT system administrator have not told you how many users/companies are sharing the same Network/Cable Internet connection--what if 5,000 users within the block are login and sharing the same 100 Mbps cable?

Using your PCs as a mail server can send between 500 to 5,000 (or more) text emails per hour using a 56Kbps or ISDN 64/128kbps depending on the Internet connection throughput, PCs capability and the mail server program used.

DSL 256/512kbps or ADSL 12/480 Mbps, Network/Cable connection will improve the mailing speed (again depend on the throughput) between 2,500 to 250,000 text emails per hour.

Network or Cable connection may even send up-to 250,000 emails per hour, depending on Internet connection throughput, computer system capability and the mail server program used.

*Multiple thread mail server programs can send large volume of emails through broadband system like: DSL, ADSL, Network or Cable connection. Single thread (freeware) or multi-thread PCs mail server available from www.argrosoft.com

MailsBroadcast mailing thread settings are independent and not the same as those from a *multi-thread mail server program settings.

MailsBroadcast mailing thread means that, if you have set it to 100; then emails will be sent in groups of 100 to your ISP mail server or to your computer mail server program. And if they (your ISP or PCs mail server) can't cache them fast enough for delivery, the mailing process will slow-down instead of faster.

MailsBroadcast mailing thread default setting is 10 and it is recommended to try various threads setting value to determine the optimal speed for sending emails to your ISP mail server or your computer mail server program.

Important notes: Speed of broadcasting emails are affected by a mail server capability and the Internet connection throughput--therefore, mailing thread setting for non-peak hours is not the same as for peak-hours. It means that different Internet connection throughput environment uses different thread settings and using higher thread settings with poor throughput will slow-down mailings.

Notes: Your mail server program *single-thread mailing--means that all your emails will be in queue or cache (stored) to be sent out, after sending out an email--it must be processed and accepted by the recipient ISP mail server before the next email can be sent.

*Multi-thread mailing--means that if your have set the mail server program (some allow you to set it) to 10 threads, then 10 emails will be sent to 10 recipients mail server simultaneously in a continuously stream without having to wait for each and every ISP mail server to respond before sending the next--meaning that at any one time there will always 10 emails being sent at the same time.




PING your ISP servers to determine connection throughput.


MTU Maximum Transmission Unit  Is the default packet Windows uses to negotiate when a connection is opened between two computers, they must agree on an MTU by comparing MTU and selecting the smaller of the two. If it is set too large for routers, it is then fragmented into packet size and can take double the amount of time it takes to send a single packet.
